Computer companies and edge providers, joined by some content creators, continued their pushback on the FCC's Restoring Internet Freedom order Thursday (Nov. 15) in a reply brief to the federal court hearing Mozilla's appeal of the order, which eliminated the rules against blocking, throttling or paid prioritization and reclassified ISPs as Title I information services.

The Computer & Communications Industry Association, along with the Entertainment Software Association, Internet Association, and the Writers Guild of America, West, filed the reply brief with the U.S. Court of Appeals. Their members include Amazon, Facebook, Google, Netflix, Microsoft, Twitter and a veritable host of others.

They had earlier filed a brief intervening in the case and arguing the FCC did not have the authority to "abdicate" the old rules.

Their view has not changed in the interim. "The Commission’s decision to eliminate all ISP conduct rules did not comply with the substantive and procedural protections of the APA and cannot stand," they told the court. That APA is the Administrative Procedures Act, which requires that agency decisions not be arbitrary or capricious.
