jriding writes: The Federal Communications Commission's new Republican leadership has rescinded a determination that ATT and Verizon Wireless violated net neutrality rules with paid data cap exemptions. The FCC also rescinded several other Wheeler-era reports and actions. The FCC released its report on the data cap exemptions (aka "zero-rating") in the final days of Democrat Tom Wheeler's chairmanship. Because new Chairman Ajit Pai opposed the investigation, the FCC has now formally closed the proceeding. The FCC's Wireless Telecommunications Bureau sent letters to ATT, Verizon, and T-Mobile USA notifying the carriers "that the Bureau has closed this inquiry. Any conclusions, preliminary or otherwise, expressed during the course of the inquiry will have no legal or other meaning or effect going forward." The FCC's Wireline Competition Bureau also sent a letter to Comcast closing an inquiry into the company's Stream TV cable service, which does not count against data caps. The FCC issued an order that "sets aside and rescinds" the Wheeler-era report on zero-rating. All "guidance, determinations, and conclusions" from that report are rescinded, and it will have no legal bearing on FCC proceedings going forward, the order said. ATT and Verizon allow their own video services (DirecTV and Go90, respectively) to stream on their mobile networks without counting against customers' data caps, while charging other video providers for the same data cap exemptions. The FCC under Wheeler determined that ATT and Verizon unreasonably interfered with online video providers' ability to compete against the carriers' video services.
