An anonymous reader writes: T-Mobile is expanding its Binge On program. The wireless carrier on Thursday announced that it is adding YouTube and seven other video services including Discovery Go, Google Play Movies, and Red Bull TV to its program which allows subscribers to stream as much as they want without billing the usage against their data plan. The carrier says that its partners can now optimize the video as well, with YouTube being the first service to make use of the feature. From an Ars Technica report, "Binge On is enabled by default and affects nearly all video regardless of whether a video provider has joined the program. Binge On throttles video streams and downloads to about 1.5Mbps, forcing the video services to deliver lower quality, typically about 480p. Video services that meet some technical requirements also get their data "zero-rated" so that customers can watch shows without it counting against high-speed data limits." Many have raised concerns about Binge On and the way it handles internet traffic. Some strongly believe that T-Mobile's program violates Net Neutrality. Earlier this year, privacy rights group, EFF, also expressed its concerns, adding that Binge On was just "throttling of all data." Interestingly, YouTube was one of the key video platforms which hadn't joined Binge On when T-Mobile first introduced the program last year. At the time, the Google-owned video portal said, "Reducing data charges can be good for users, but it doesn't justify throttling all video services, especially without explicit user consent." Not sure what made YouTube change its heart.
