"SpaceX has launched 20 of its Starlink satellites up into Earth's orbit, enabling direct-to-cellphone connectivity for subscribers anywhere on the planet," reports the tech blog New Atlas. That completes the constellation's first orbital shell, following a launch of an initial batch of six satellites for testing back in January. The satellites were launched with a Falcon 9 rocket from California's Vandenberg Space Force Base on December 5 at 10 PM EST; they were then deployed in low Earth orbit. SpaceX founder Elon Musk noted on X that the effort will "enable unmodified cellphones to have internet connectivity in remote areas." He added a caveat for the first orbital shell — "Bandwidth per beam is only ~10 Mb, but future constellations will be much more capable...."

The big deal with this new venture is that unlike previous attempts at providing satellite-to-phone service, you don't need a special handset or even a specific app to get access anywhere in the world. Starlink uses standard LTE/4G protocols that most phones are compatible with, partners with mobile operators like T-Mobile in the U.S. and Rogers in Canada, and has devised a system to make its service work seamlessly with your phone when it's connecting to satellites 340 miles (540 km) above the Earth's surface. The SpaceX division noted it's also worked out latency constraints, ideal altitudes and elevation angles for its satellites, along with several other parameters, to achieve reliable connectivity. Each satellite has an LTE modem on board, and these satellites plug into the massive constellation of 6,799 existing Starlink spacecraft, according to Space.com.

Connecting to that larger constellation happens via laser backhaul, where laser-based optical communication systems transmit data between satellites. This method leverages the advantages of lasers over traditional radio frequency communications, enabling data rates up to 100 times faster, increased bandwidth, and improved security.
The direct-to-cell program was approved last month, the article points out — but it's ready to ramp up. "You'll currently get only text service through the end of 2024; voice and data will become available sometime next year, as will support for IoT devices (such as smart home gadgets). The company hasn't said how much its service will cost. " (They also note there's already competing services from Lynk, "which has satellites in orbit and launched in the island nation of Palau back in 2023, and AST SpaceMobile, which also has commercial satellites in orbit and contracts with the U.S. government, Europe, and Japan.")

Elon Musk's announcement on X.com prompted this interesting exchange:

X.com User: You've stated that purchasing Starlink goes toward funding the journey to Mars, yes?

Elon Musk: Yes.

An anonymous reader shared this report from NBC News: Amid an unprecedented cyberattack on telecommunications companies such as AT&T and Verizon, U.S. officials have recommended that Americans use encrypted messaging apps to ensure their communications stay hidden from foreign hackers...

In the call Tuesday, two officials — a senior FBI official who asked not to be named and Jeff Greene, executive assistant director for cybersecurity at the Cybersecurity and Infrastructure Security Agency — both recommended using encrypted messaging apps to Americans who want to minimize the chances of China's intercepting their communications. "Our suggestion, what we have told folks internally, is not new here: Encryption is your friend, whether it's on text messaging or if you have the capacity to use encrypted voice communication. Even if the adversary is able to intercept the data, if it is encrypted, it will make it impossible," Greene said. The FBI official said, "People looking to further protect their mobile device communications would benefit from considering using a cellphone that automatically receives timely operating system updates, responsibly managed encryption and phishing resistant" multi-factor authentication for email, social media and collaboration tool accounts...

The FBI and other federal law enforcement agencies have a complicated relationship with encryption technology, historically advocating against full end-to-end encryption that does not allow law enforcement access to digital material even with warrants. But the FBI has also supported forms of encryption that do allow some law enforcement access in certain circumstances.
Officials said the breach seems to include some live calls of specfic targets and also call records (showing numbers called and when). "The hackers focused on records around the Washington, D.C., area, and the FBI does not plan to alert people whose phone metadata was accessed."

"The scope of the telecom compromise is so significant, Greene said, that it was 'impossible" for the agencies "to predict a time frame on when we'll have full eviction.'"

China-linked spies are still lurking inside U.S. telecommunications networks roughly six months after American officials started investigating the intrusions, senior officials told reporters Tuesday. From a report: This is the first time U.S. officials have confirmed reports that Salt Typhoon hackers still have access to critical infrastructure -- and they're proving difficult to kick out. Officials added that they don't yet know the full scope of the intrusions, despite starting the investigation in late spring.

The Cybersecurity and Infrastructure Security Agency and FBI released guidance Tuesday for the communications sector to harden their networks against Chinese state-sponsored hackers. The guide includes basic steps like maintaining logs of activity on the network, keeping an inventory of all devices in the telecom's environment and changing any default equipment passwords. The hack has given Salt Typhoon unprecedented access to records from U.S. telecommunications networks about who Americans are communicating with, a senior FBI official told reporters during a briefing.

The FCC said it has approved a license for T-Mobile and SpaceX's Starlink to provide supplemental coverage to cover internet dead zones. Reuters reports: The license marks the first time the FCC has authorized a satellite operator collaborating with a wireless carrier to provide supplemental telecommunications coverage from space on some flexible-use spectrum bands allocated to terrestrial service. The partnership aims to extend the reach of wireless networks to remote areas and eliminate "dead zones."

T-Mobile and SpaceX announced a partnership in 2022 and in January the first set of satellites supporting the partnership was launched into low-Earth orbit with SpaceX's Falcon 9 rocket. "The FCC is actively promoting competition in the space economy by supporting more partnerships between terrestrial mobile carriers and satellite operators to deliver on a single network future that will put an end to mobile dead zones," said FCC Chair Jessica Rosenworcel.

Ars Technica's Jon Brodkin reports: Lobby groups for Internet service providers claim that ISPs' customer service is so good already that the government shouldn't consider any new regulations to mandate improvements. They also claim ISPs face so much competition that market forces require providers to treat their customers well or lose them to competitors. Cable lobby group NCTA-The Internet & Television Association told the Federal Communications Commission in a filing (PDF) that "providing high-quality products and services and a positive customer experience is a competitive necessity in today's robust communications marketplace. To attract and retain customers, NCTA's cable operator members continuously strive to ensure that the customer support they provide is effective and user-friendly. Given these strong marketplace imperatives, new regulations that would micromanage providers' customer service operations are unnecessary."

Lobby groups filed comments in response to an FCC review of customer service that was announced last month, before the presidential election. While the FCC's current Democratic leadership is interested in regulating customer service practices, the Republicans who will soon take over opposed the inquiry. USTelecom, which represents telcos such as AT&T and Verizon, said that "the competitive broadband marketplace leaves providers of broadband and other communications services no choice but to provide their customers with not only high-quality broadband, but also high-quality customer service."

"If a provider fails to efficiently resolve an issue, they risk losing not only that customer -- and not just for the one service, but potentially for all of the bundled services offered to that customer -- but also any prospective customers that come across a negative review online. Because of this, broadband providers know that their success is dependent upon providing and maintaining excellent customer service," USTelecom wrote. While the FCC Notice of Inquiry said that providers should "offer live customer service representative support by phone within a reasonable timeframe," USTelecom's filing touted the customer service abilities of AI chatbots. "AI chat agents will only get better at addressing customers' needs more quickly over time -- and if providers fail to provide the customer service and engagement options that their customers expect and fail to resolve their customers' concerns, they may soon find that the consumer is no longer a customer, having switched to another competitive offering," the lobby group said.

An anonymous reader quotes a report from Ars Technica: The Supreme Court signaled it may take up a case that could determine whether Internet service providers must terminate users who are accused of copyright infringement. In an order (PDF) issued today, the court invited the Department of Justice's solicitor general to file a brief "expressing the views of the United States."

In Sony Music Entertainment v. Cox Communications, the major record labels argue that cable provider Cox should be held liable for failing to terminate users who were repeatedly flagged for infringement based on their IP addresses being connected to torrent downloads. There was a mixed ruling at the US Court of Appeals for the 4th Circuit as the appeals court affirmed a jury's finding that Cox was guilty of willful contributory infringement but reversed a verdict on vicarious infringement "because Cox did not profit from its subscribers' acts of infringement." That ruling vacated a $1 billion damages award and ordered a new damages trial. Cox and Sony are both seeking a Supreme Court review. Cox wants to overturn the finding of willful contributory infringement, while Sony wants to reinstate the $1 billion verdict.

The Supreme Court asking for US input on Sony v. Cox could be a precursor to the high court taking up the case. For example, the court last year asked the solicitor general to weigh in on Texas and Florida laws that restricted how social media companies can moderate their platforms. The court subsequently took up the case and vacated lower-court rulings, making it clear that content moderation is protected by the First Amendment.

"Get your head examined. And get the fuck out of here with this shit." That's how Bcachefs developer Kent Overstreet ended a post on the Linux kernel mailing list.

This was followed by "insufficient action to restore the community's faith in having otherwise productive technical discussions without the fear of personal attacks," according to an official ruling by committee enforcing the kernel community's code of conduct. After formalizing an updated enforcement process for unacceptable behaviors, it then recommended that during the Linux 6.13 kernel development cycle, Overstreet's participation should be restricted (with his pull requests declined). Phoronix covered their ruling, and ItsFOSS and The Register offer some of the backstory.

Overstreet had already acknowledged that "Things really went off the rails (and I lost my cool, and earned the ire of the CoC committee)" in a 6,200-word blog post on his Patreon page. But he also emphasized that "I'm going to keep writing code no matter what. Things may turn into more of a hassle to actually get the code, but people who want to keep running bcachefs will always be able to (that's the beauty of open source, we can always fork), and I will keep supporting my users..."

More excerpts from Overstreet's blog post: I got an emails from multiple people, including from Linus, to the effect of "trust me, you don't want to be known as an asshole — you should probably send him an apology"... Linus is a genuinely good guy: I know a lot of people reading this will have also seen our pull request arguments, so I specifically wanted to say that here: I think he and I do get under each other's skin, but those arguments are the kind of arguments you get between people who care deeply about their work and simply have different perspectives on the situation...

[M]y response was to say "no" to a public apology, for a variety of reasons: because this was the result of an ongoing situation that had now impacted two different teams and projects, and I think that issue needs attention — and I think there's broader issues at stake here, regarding the CoC board. But mostly, because that kind of thing feels like it ought to be kept personal... I'd like a better process that isn't so heavy handed for dealing with situations where tensions rise and communications break down. As for that process: just talk to people... [W]e're a community. We're not interchangeable cogs to be kicked out and replaced when someone is "causing a problem", we should be watching out for each other...

Another note that I was raising with the CoC is that a culture of dismissiveness, of finding ways to avoid the technical discussions we're supposed to be having, really is toxic, and moreso than mere flamewars... we really do need to be engaging properly with each other in order to do our work well.
After the official response from the committee, Overstreet responded on the kernel mailing list. "I do want to apologize for things getting this heated the other day, but I need to also tell you why I reacted the way I did... I do take correctness issues very seriously, and I will get frosty or genuinely angry if they're being ignored or brushed aside."

Reddit's moderators drew some criticism after "locking" a discussion about C++ paper/proposal author Andrew Tomazos. The URL (in the post with the locked discussion) had led to a submission for Slashdot's queue of potential (but unpublished) stories, which nevertheless attracted 178 upvotes on Reddit and another 85 comments. That unpublished Slashdot submission was also submitted to Hacker News, where it drew another 38 upvotes but was also eventually flagged.

Back on Reddit's C++ subreddit (which has 300,000 members), a "direct appeal" was submitted to the moderators to unlock Reddit's earlier discussion (drawing over 100 upvotes). But there's one problem with this drama, as Slashdot reader brantondaveperson pointed out. "There appears to be no independent confirmation of this story anywhere. The only references to it are this Slashdot story, and a Reddit story. Neither cite sources or provide evidence." This drew a response from the person submitting the potential story to Slashdot: You raise a valid point. The communication around this was private. The complaint about the [paper's] title, the author's response, and the decision to expel were all communicated by either private email, on private mailing lists or in private in-person meetings. These private communications could be quoted by participants in said communications. Please let us know if that would be sufficient.
The paper had already drawn some criticism in a longer blog post by programmer Izzy Muerte (which called it "a fucking cleaned up transcript of a ChatGPT conversation".) It's one of six papers submitted this year by Tomaszos to the ISO's "WG21" C++ committee. Tomazos (according to his LinkedIn profile) is "lead programmer" of videogame company Fury Games (founded by him and his wife). It also shows an earlier two-year stint as a Google senior software engineer.

There were two people claiming direct knowledge of the situation posting on Reddit. A user named kritzikratzi posted: I contacted Andrew Tomazos directly. According to him the title "The Undefined Behavior Question" caused complaints inside WG21. The Standard C++ Foundation then offered two choices (1) change the paper title (2) be expelled. Andrew Tomazos chose (2).
A Reddit user Dragdu posted: He wasn't expelled for that paper, but rather this was the last straw. And he wasn't banned from the [WG21] committee, that is borderline impossible, but rather the organization he was representing told him to fuck off and don't represent them anymore. If he can find different organization to represent, he can still attend... Tomazos has been on lot of people's shit list, because his contributions suck... He decided that the title is too important to his ViSiOn for the chatgpt BS submitted as a paper, and that he won't change the title. This was the straw that broke the camel's back and his "sponsor" told him to fuck off....
There was also some back-and-forth on Hacker News. bun_terminator: r/cpp mods just woke up, banning everyone who question... this lunatic behavior.

(Reddit moderator): We did not go on a banning spree, we banned only one person, you. After removing the comment where you insulted someone, I checked your history, noticed that you did not meaningfully participate in r/cpp outside this thread, and decided to remove someone from the community who'd only be there to cause trouble.

An anonymous reader quotes a report from Ars Technica: DirecTV is pulling out of an agreement to buy its satellite rival Dish after bondholders objected to terms of the deal. DirecTV issued an announcement last night saying "it has notified EchoStar of its election to terminate, effective as of 11:59 p.m., ET on Friday, November 22nd, 2024, the Equity Purchase Agreement (EPA) pursuant to which it had agreed to acquire EchoStar's video distribution business, Dish DBS."

In the deal announced on September 30, DirecTV was going to buy the Dish satellite TV and Sling TV streaming business from EchoStar for a nominal fee of $1. DirecTV would have taken on $9.75 billion of Dish debt if the transaction moved ahead. The deal did not include the Dish Network cellular business. Dish bondholders quickly objected to terms requiring them to take a loss on the value of their debt. DirecTV had said Dish notes would be exchanged with "a reduced principal amount of DirecTV debt which will have terms and collateral that mirror DirecTV's existing secured debt." The principal amount would have been reduced by at least $1.568 billion.

DirecTV last night said it is now exercising its right to terminate the acquisition because noteholders did not accept the exchange offer. "The termination of the Agreement follows Dish DBS noteholders' failure to agree to the proposed Exchange Debt Offer Terms issued by EchoStar, which was a condition of DirecTV's obligations to acquire Dish under the EPA," the press release said. DirecTV CEO Bill Morrow indicated his company wasn't willing to change the deal to satisfy Dish bondholders. "We have terminated the transaction because the proposed Exchange Terms were necessary to protect DirecTV's balance sheet and our operational flexibility," Morrow said.

Damage to two undersea fiber-optic cables in the Baltic Sea this month points to growing vulnerability of critical submarine infrastructure, with German officials suspecting sabotage and Swedish police investigating a Chinese cargo vessel's involvement.

The incident highlights escalating risks to the global submarine cable network, which carries 99% of international telecommunications traffic through 530 cable systems spanning 850,000 miles. These garden hose-thick cables facilitate trillions in daily financial transactions and vital government communications.

Security experts warn that Russia has increased monitoring of undersea cables amid tensions over Ukraine. Taiwan reported 36 cable damages by foreign vessels since 2019, while Houthi rebels denied targeting Red Sea cables this year. Though most of the 100-plus annual cable faults are accidental, deliberate sabotage remains a concern. Repairs are costly, with new transatlantic cables running up to $250 million.

The Federal Communications Commission voted on Thursday to propose new rules governing undersea internet cables in the face of growing security concerns, as part of a review of regulations on the links that handle nearly all the world's online traffic. From a report: The FCC voted 5-0 on proposed updates to address the national security concerns over the global network of more than 400 subsea cables that handle more than 98% of international internet traffic. [...]

Baltic nations said this week they are investigating whether the cutting of two fiber-optic undersea telecommunication cables in the Baltic Sea was sabotage. Rosenworcel noted that in 2023 Taiwan accused two Chinese vessels of cutting the only two cables that support internet access on the Matsu Islands and Houthi attacks in the Red Sea may have been responsible for the cutting of three cables providing internet service to Europe and Asia.

An anonymous reader shares a report: A recent survey from Global System for Mobile Communications Association Intelligence (GSMA), the research wing of a U.K.-based organization that represents mobile operators around the world, found that 4.6 billion people across the globe are now connected to mobile internet -- or roughly 57% of the world's population. Now, the rate of new mobile internet subscriber growth is slowing. From 2015 to 2021, the survey consistently found over 200 million coming online through mobile devices around the world each year. But in the last two years, that number has dropped to 160 million.

Rest of World analysis of that data found that a number of developing countries are plateauing in the number of mobile internet subscribers. That suggests that in countries like Pakistan, Bangladesh, Nigeria, and Mexico, the easiest populations to get online have already logged on, and getting the rest of the population on mobile internet will continue to be a challenge. GSMA collects data by surveying a nationally representative sample of people in each country, and then it correlates the results with similar studies.

[...] In countries including China, the U.S., and Singapore, a high share of the population is already connected to mobile internet -- 80%, 81%, and 93%, respectively. So it's no surprise that the rate of mobile internet subscriptions has slowed. But the rate of new users has also slowed in countries including Bangladesh, Nigeria, and Pakistan -- where only 37%, 34%, and 24% of the population currently use mobile internet.

The Verge's Richard Lawler reports: Strava recently informed its users and partners that new terms for its API restrict the data that third-party apps can show, refrain from replicating Strava's look, and place a ban on using data "for any model training related to artificial intelligence, machine learning or similar applications." The policy is effective as of November 11th, even though Strava's own post about the change is dated November 15th.

There are plenty of posts on social media complaining about the sudden shift, but one place where dissent won't be tolerated is Strava's own forums. The company says, "...posts requesting or attempting to have Strava revert business decisions will not be permitted." Brian Bell, Strava's VP of Communications and Social Impact, said in a statement: "We anticipate that these changes will affect only a small fraction (less than .1 percent) of the applications on the Strava platform -- the overwhelming majority of existing use cases are still allowed, including coaching platforms focused on providing feedback to users and tools that help users understand their data and performance."

Donald Trump has named FCC Commissioner Brendan Carr to chair the U.S. communications regulator when he takes office in January 2025, citing Carr's stance against what Trump called "regulatory lawfare." Carr, a lawyer and longtime Republican who has served at the FCC under both Trump and Biden administrations, has emerged as a vocal critic of major social media companies' content moderation practices.

"Humbled and honored" by the appointment, Carr pledged on X to "dismantle the censorship cartel." As the FCC's senior Republican commissioner, Carr has advocated for stricter oversight of technology companies, pushing for transparency rules on platforms like Google and Facebook, expanded rural broadband access, and tougher restrictions on Chinese-owned TikTok. Trump praised Carr as a "warrior for free speech" while announcing the appointment. During his campaign, Trump has said he would seek to revoke licenses of television networks he views as biased.

Chinese hackers, reportedly linked to a Chinese intelligence agency, breached T-Mobile as part of a broader cyber-espionage campaign targeting telecom companies to spy on high-value intelligence targets. "T-Mobile is closely monitoring this industry-wide attack, and at this time, T-Mobile systems and data have not been impacted in any significant way, and we have no evidence of impacts to customer information," a company spokesperson told the Wall Street Journal. Reuters reports: It was unclear what information, if any, was taken about T-Mobile customers' calls and communications records, according to the report. On Wednesday, The Federal Bureau of Investigation (FBI) and the U.S. cyber watchdog agency CISA said China-linked hackers have intercepted surveillance data intended for American law enforcement agencies after breaking into an unspecified number of telecom companies.

Economist: Britain has long been a pioneer in telecoms. In 1837 it built the world's first commercial telegraph; the first transatlantic call was placed from London in 1927; in 1992 a British programmer sent the first text message to a mobile phone. Today it lags rather than leads. According to figures provided to The Economist by Opensignal, a research firm, Britain ranks 46th for download speeds out of the 56 developed and developing countries for which there are data. That gives it the worst mobile service in the rich world.

Some of this is due to demand. Over the past three years data usage on mobile devices has doubled as people stream films and play games. The busiest parts of cities often lack mobile reception because the system is at capacity. But mainly it is an issue of supply. British users of 5G are only on it 11% of the time. That puts Britain 43rd out of the 56 countries. This lacklustre performance is caused by a combination of government U-turns, insufficient investment and sclerotic planning.

An anonymous reader quotes a report from Bloomberg: The Australian government plans to enact laws requiring big tech firms to protect its citizens online, the latest move by the center-left Labor administration to crack down on social media including through age limits and curbs on misinformation. Communications Minister Michelle Rowland announced the government's plan for a legislated Digital Duty of Care in Australia on Wednesday night, saying it aligned with similar laws in the UK and European Union. "It is now time for industry to show leadership, and for social media to recognize it has a social responsibility," Rowland said in a speech in Sydney announcing the measures. It would "keep users safe and help prevent online harms."

In response to the laws, Facebook and Instagram operator Meta Platforms Inc. called for the restrictions to be handled by app stores, such as those run by Google and Apple Inc., rather than the platforms themselves. The government has ignored those requests, but has yet to announce what fines companies would face or what age verification information will need to be provided. At the same time, Albanese has moved forward controversial laws to target misinformation and disinformation online, which opponents have labeled an attack on freedom of speech. Earlier this month, Albanese said the government would legislate for a ban on social media for children under 16, a policy the government says is world-leading. "Social media is doing harm to our kids and I'm calling time on it," Albanese told a news conference.

Wi-Fi 8 (also known as IEEE 802.11bn Ultra High Reliability) is expected to arrive around 2028, prioritizing an enhanced user experience over speed by optimizing interactions between devices and access points. While it retains similar bandwidth specifications as the previous standard, Wi-Fi 8 aims to improve network efficiency, reducing interference and congestion for a more reliable and adaptive connection. PCWorld's Mark Hachman reports: As of Nov. 2024, MediaTek believes that Wi-Fi 8 will look virtually identical to Wi-Fi 7 in several key areas: The maximum physical layer (PHY) rate will be the same at 2,880Mbps x 8, or 23Gbits/s. It will also use the same four frequency bands (2, 4, 5, and 6GHz) and the same 4096 QAM modulation across a maximum channel bandwidth of 320MHz. (A Wi-Fi 8 router won't get 23Gbps of bandwidth, of course. According to MediaTek, the actual peak throughput in a "clean," or laboratory, environment is just 80 percent or so of the hypothetical peak throughput, and actual, real-world results can be far less.)

Still, put simply, Wi-Fi 8 should deliver the same wireless bandwidth as Wi-Fi 7, using the same channels and the same modulation. Every Wi-Fi standard has also been backwards-compatible with its predecessors, too. What Wi-Fi 8 will do, though, is change how your client device, such as a PC or a phone, interacts with multiple access points. Think of this as an evolution of how your laptop talks to your home's networking equipment. Over time, Wi-Fi has evolved from communications between one laptop and a router, across a single channel. Channel hopping routed different clients to different bands. When Wi-Fi 6 was developed, a dedicated 6GHz channel was added, sometimes as a dedicated "backhaul" between your home's access points. Now, mesh networks are more common, giving your laptop a variety of access points, channels, and frequencies to select between. For a detailed breakdown of the upcoming advancements coming to Wi-Fi 8, including Coordinated Spatial Reuse, Coordinated Beamforming, and Dynamic Sub-Channel Operation, read the full article.

The UK's oldest satellite, Skynet-1A, mysteriously shifted from its original orbit above East Africa to a new position over the Americas, likely due to a mid-1970s command whose origins remain unknown. "The question is who that was and with what authority and purpose?" asks the BBC. From the report: "It's still relevant because whoever did move Skynet-1A did us few favours," says space consultant Dr Stuart Eves. "It's now in what we call a 'gravity well' at 105 degrees West longitude, wandering backwards and forwards like a marble at the bottom of a bowl. And unfortunately this brings it close to other satellite traffic on a regular basis. "Because it's dead, the risk is it might bump into something, and because it's 'our' satellite we're still responsible for it," he explains.

Dr Eves has looked through old satellite catalogues, the National Archives and spoken to satellite experts worldwide, but he can find no clues to the end-of-life behaviour of Britain's oldest spacecraft. It might be tempting to reach for a conspiracy theory or two, not least because it's hard to hear the name "Skynet" without thinking of the malevolent, self-aware artificial intelligence (AI) system in The Terminator movie franchise. But there's no connection other than the name and, in any case, real life is always more prosaic.

Starting November 11, TSMC plans to stop supplying 7 nm and smaller chips to Chinese companies working on AI processors and GPUs. "The move is reportedly to ensure it remains compliant with US export restrictions," reports The Register. From the report: This will not affect Chinese customers wanting 7 nm chips from TSMC for other applications such as mobile and communications, according to Nikkei, which said the overall impact on the chipmaker's revenue is likely to be minimal. TrendForce further cites another China-based source who claims the move was at the behest of the US Department of Commerce, which informed TSMC that any such shipments should not proceed unless approved and licensed by its BIS (Bureau of Industry and Security). We asked the agency for confirmation.

Any moves by the silicon supremo is likely to be out of caution to pre-empt accusations from Washington that it isn't doing enough to prevent advanced technology from getting into the hands of Chinese entities that have been sanctioned. As TrendForce notes, it "highlights the foundry giant's delicate position in the global semiconductor supply chain amid the heating chip war between the world's two superpowers."
