Chrome's 'Topics' Advertising System Is Here, Whether You Want It Or Not (arstechnica.com) 86

slack_justyb writes: After the failure of the Chrome user-tracking system that was called FLoC, Google's latest try at topic tracking to replace the 3rd party cookie (that Chrome is the only browser to still support) is FLEDGE and the most recent drop of Canary has this on full display for users and privacy advocates to dive deeper into. This recent release shows Google's hand that it views user tracking as a mandatory part of internet usage, especially given this system's eye-rolling name of "Privacy Sandbox" and the tightness in the coupling of this new API to the browser directly.

The new API will allow the browser itself to build what it believes to be things that you are interested in, based on broad topics that Google creates. New topics and methods for how you are placed into those topics will be added to the browser's database and indexing software via updates from Google. The main point to take away here though is that the topic database is built using your CPU's time. At this time, opting out of the browser building this interest database is possible thus saving you a few cycles from being used for that purpose. In the future there may not be a way to stop the browser from using cycles to build the database; the only means may be to just constantly remove all interest from your personal database. At this time there doesn't seem to be any way to completely turn off the underlying API. A website that expects this API will always succeed in "some sort of response" so long as you are using Chrome. The response may be that you are interested in nothing, but a response none-the-less. Of course, sending a response of "interested in nothing" would more than likely require someone constantly, and timely, clearing out the interest database, especially if at some later time the option to turn off the building of the database is removed.

With 82% of Google's empire based on ad revenue, this latest development in Chrome shows that Google is not keen on any moves to threaten their main money maker. Google continues to argue that it is mandatory that it builds a user tracking and advertising system into Chrome, and the company says it won't block third-party cookies until it accomplishes that -- no matter what the final solution may ultimately be. The upshot, if it can be called that, of the FLEDGE API over FLoC, is that abuse of FLEDGE looks to yield less valuable results. And attempting to use the API alone to pick out an individual user via fingerprinting or other methods employed elsewhere seems to be rather difficult to do. But only time will tell if that remains true or just Google idealizing this new API.
As for the current timeline, here's what the company had to say in the latest Chromium Blog post: "Starting today, developers can begin testing globally the Topics, FLEDGE, and Attribution Reporting APIs in the Canary version of Chrome. We'll progress to a limited number of Chrome Beta users as soon as possible. Once things are working smoothly in Beta, we'll make API testing available in the stable version of Chrome to expand testing to more Chrome users."

  • They got to shift to just the topic of interest at that instant only. No history what so ever. In other words, *any* tracking API is wrong.

    • Google tried "just the topic of interest at that instant only"; the initial version of AdSense was contextual. It turned out that advertisers weren't willing to pay nearly as much for ad placements targeted at the immediate context of an individual HTML document as they are for that ad placements that target an individual viewer's interests over the longer term.

      I'm interested in ideas to replace advertising that don't involve putting every domain behind a separate subscription.

        But this is the s*** we're worried about? Priorities people. Priorities.

        Well first off, last I checked this wasn't a site about housing markets. *eyerolling ensues* It, at least professes, to be a technology website. I know politics and literally everything that isn't tech has slowly crawled onto this site. But I think you're ranking this much higher that anyone else would about this tech topic on a tech website. I mean if you want to complain about housing, so be it. But I think Reddit would better serve you, just saying.

        That said.

        You can literally just compile them without the advertisement stuff

        Yes, but you cannot compile Chrome without the ad stuff. Chrome is a closed source project that is built on top of the open source Chromium project. You can have Chromium without the ads, you can Brave without the ads, you can have Edge without the ads, but you can never have Chrome without the ads. And that may seem, insignificant to any of us here. We understand the difference, we might be able to tell our PHB at work to swap to Edge or something else. But for many, they're head deep into Google's services like Workspace. Google doesn't support tickets on browsers not Chrome and if your company is paying for that support, you don't have a choice anymore. Or some people don't know there are others. Or some people don't care that their are others. And so on, the reasons are varied and an exhaustive list of all of them is beside the point. The point being, for one reason or another, "just use some other project" isn't an option to some. And just tossing up this kind of excuse of "just use something else" really boils down to hand waving away an actual problem. And that hand waving is what gives tech giants the required wiggle room to enact the very things we eventually start complaining about years after the fact. We bemoan actual abuse by corporate giants but we tend to fail in being proactive in preventing it from happening over and over and over. And then when there is actual abuse, we all stand around looking at each other either saying "I told you so" or "How did we let it get this far?"

        I get that we on our own little PCs have the luxury of just jumping ship whenever we feel like it. But our situation is the exception to the norm. And it is important to keep that perspective in mind.

        There's several projects that do just that and binaries are readily available

        Yes, you are correct. But they are not Chrome. And until the dominance of Chrome is toppled, those other projects aren't really meaningful. Across all device types (last I checked somewhere near end of 2021) Chrome is two out of every three browser request on this planet. Not Chromium, not Brave, not Edge, nor anything else. Chrome. So yes those other projects do exist, but they exist as such that if they did not exist there would be little to no one who noticed.

        Frankly with all the other things in the world to worry about having some advertiser knowing what my preferred flavor of potato chip is is the least of my worries

        And that's fine, everyone is free to value their personal preferences differently. Chrome however, takes my ability to rank the value of my preferences away from me. Google has determined exactly what the value of those preferences are and give people no say on adjustment to that value. It's one thing to say, "yeah what potato chip I like means really nothing to me in the long run." It is another thing entirely to have no say if those potato chips mean anything to you. With Chrome, it doesn't matter if you value it or not. That was never an option to voice with Chrome. So indicating that you do or don't care is beside the point, you were never given an option to indicate that it is important or not in the first place with Chrome. Your opinion is meaningless because you are never given an option to where your opinion of things impacts Chrome.

    • Well, you said it yourself - you sill need a few "qol extensions", probably uBlock and friends. The system created by Google could be used to block content based on user preferences, if only we could use it for our own benefit. It's capable of quickly learning from user preferences, it would make wonders filtering feeds and re-ranking search results according to our wishes. We need to bring the internet under user submission.

    • It would be nice if web developers would stop sucking Google's teat and actually support some alternative browsers. I'm sick of visiting web sites only to see a completely blank page, or being told my browser is "out of date", because modern designers think standards compliance and graceful degradation are passé.

          The same search worked in Chrome.

          So, it does happen on occasion, hence why I keep alternative browsers on hand. For the most part, though, Firefox is a superior experience for me, and has been for many years.

        • I also use Firefox pretty much 100% exclusively, and I frequently get a nice white blank page.. I've come to the conclusion that this is telling me I don't need to see what the page contains. Fortuanately, websites that are critically important to me don't do this.. so far.. knock on wood...

      I was involved with the design review of FLoC that ultimately lead to it being killed off, and Topics being created.

      FLoC was fundamentally flawed because it could be abused to gather more information about the target than was intended, and because it lacked sufficient safeguards to protect people's privacy (e.g. their sexual orientation could be inferred, or that a Muslim enjoyed eating pork).

      Topics has fixed most of it, and the few remaining issues can be worked around by browser developers and with add-ons. Also, you can completely turn it off.

      Overall I think Topics is a good thing, as long as Google follows through with heavily restricting cookies and other methods of tracking. They have to offer an alternative to avoid anti-trust issues, and this alternative does a decent job of protecting the user's privacy.

      Most importantly it means that people who want even more privacy than Topics offers will have an easier time of it. Right now privacy enhancements break a lot of websites, but if Chrome and other major browsers make them the default behaviour then sites will have to fix themselves.

          Well that's the point of Topics, you aren't being tracked at all. Everything is local. It actively prevents companies from tracking you.

          • Imagine that the topics define a vector space. How the topics evolve over time will provide more information about an individual than an individual topic. Yes, there is some entropy being introduced when topics are picked, but it is debatable if it will be enough.
            • by AmiMoJo ( 196126 )

              The problem is you can't easily tie the topics to an identity, unless your website happens to use logins in which case it's no worse than what we have now.

              In other words unless the user voluntarily creates an account, you can't observe changes over time.

          • by DarkOx ( 621550 )

            I don't see how it accomplishes anything of the sort. Google still ultimately knows which ads the serve you. If the topics are allowed to be granular enough - user-agent + ip + some set of ads recently served; is going to unique you based on some set of intersection of topics.

              It's designed not to be granular enough. As I say, they get one of five possible topics and a random one, and the topics change every week. It always uses the domain of the top level frame too, so 3rd party embedded stuff doesn't get a different topic.

              Google is also changing the user-agent to stop it being used for fingerprinting: https://developer.chrome.com/d... [chrome.com]

              Okay, so let's say some company has a large number of websites under its control, it is possible that they could identify an individual with some level of certainty based on collecting all 5+N of their topics and IP address and maybe some other fingerprinting stuff. And maybe they could tie that to a real identity if the user happens to have an account on one of those sites. But that's a hell of a lot of work for a low quality identifier that requires the user to visit several of the company's sites, and lasts a maximum of a week. All to deliver slightly better targeted ads than the topics they get with zero effort offer.

              It's not perfect, but it's a hell of a lot better than what we have, and nobody is stopping you from adding your own additional protections.

        That's not how Topics works.

        When you visit a site that uses Topics, the site gets one topic that you are interested in. The list of topics is maintained by Google and the IAB, and you can browse it here: https://github.com/jkarlin/top... [github.com]

        The browser randomly selects between one of the top 5 topics you are interested in, or 5% of the time a completely random one. It is done per domain and once a topic has been revealed to a domain it won't change for one week.

        In order to get a topic, the site must also offer a topic that describes its content. Sites which do not offer topics are not considered at all by the browser. The browser keeps all data locally, nothing is sent to Google. Chrome will offer a switch to turn Topics off, or it can be trivially blocked by an add-on like uBlock Origin or Privacy Badger.

        If the browser doesn't have enough information to offer topics, or if the user is in Private Browsing mode, no topic will be shared with the site. Users who disable or block the API will be indistinguishable from those with recent installs, who cleared browser data or who are in Private Browsing mode. This is very important for users of ad blockers and privacy enhancers, because the behaviour of those things is no longer distinguishable from non-users.

        Eventually, Google will severely restrict the use of cookies. They have already begun doing this, with some cookies being automatically deleted before they expire, and restrictions on 3rd party cookie use. The Topics API is the alternative, eventually cookies will only be usable for things like staying logged in.

        This seems like a reasonable compromise to me. Targeted advertising is possible, but the ability of sites to track users is severely restricted. It's not perfect, it can't be because e.g. there is no simple way to hide your IP address from the site you are visiting, and logging into sites necessarily identifies the user. It's far better than what we have though, and unlike FLoC uses a curated list of topics that avoid most of the pitfalls from that system. Most importantly, if you want to block it, doing so is trivial and won't break sites.

          Seems reasonable, and a lot more compliant with the GDPR than the current way of working. It will depend on how much control you get over the topics, though, but in the main I think this is a step forward.

            I already do both of those, and sites work fine. In fact I'm even more aggressive, I whitelist sites that don't have their cookies deleted 60 seconds after I navigate away. Logins and shopping carts still work.

        Actually it would be nice to have that information for the benefit of the user - a way to do topic detection while browsing. It could be used to reject any kind of content we don't want to see (act like AdBlock), but it would learn quickly with a few examples and be customisable per user.

        The problem is not the ML model for topic detection, but who's benefiting from it.

    But what is the alternative? Every site behind a paywall? Occasional calls for funding a la Wikipedia? Sites only owned by the rich that can afford to bleed money to push their agenda?

    Before you say "just make static ads", I was on the Internet back when that was the norm, and that was the reason people blocked those ads "it's not like I'm going to buy {{non-targeted product}}"

      Well, that's hard luck then. I don't care if 90% of websites go bust. I don't really care if every website that I use which depends on adverts goes bust. I lived without them before and I can live without them again. I don't owe them squat because the vast majority of them just publish stuff their users wrote and those users would still write stuff if we all went back to usenet and 5MB downloads of CSS to read a three line post from 10 years ago became a distant and fading nightmare.

      The ads are fine. The tracking is not.

      The alternative is to target the advertising using the one piece of information everybody knows and expects they have: what website you are looking at. This is how radio and tv and virtually all other advertisements work.

  • People pay money to avoid ads, IDC what they are based on. Don't tell me what I want or like, I will tell you!
