"Recently, there has been quite a bit of a controversy surrounding T-Mobile’s Binge On program, which doesn’t count some video data
towards customers’ data plans. A Stanford researcher, Barbara van Schewick, released a study concluding that T-Mobile’s Binge On is “likely illegal” and violates the FCC’s net neutrality rules.
Van Schewick said that although users can watch an unlimited amount of video from Binge On participants such as Netflix, they can watch at most four and a half hours per month (or just nine minutes a day), from competitors’ services. This looks like a serious distortion of competition in the video market."
