A leading lobbying group for Amazon, Facebook, Google, Netflix, Twitter and other tech giants said Friday that it would be joining the coming legal crusade to restore the U.S. government's net neutrality rules. From a report: The Washington, D.C.-based Internet Association specifically plans to join a lawsuit as an intervening party, aiding the challenge to FCC Chairman Ajit Pai's vote in December to repeal regulations that required internet providers like AT&T and Comcast to treat all web traffic equally, its leader confirmed to Recode. Technically, the Internet Association isn't filing its own lawsuit. That task will fall to companies like Etsy, public advocates like Free Press and state attorneys general, all of which plan to contend they are most directly harmed by Pai's decision, as Recode first reported this week. As an intervener, though, the Internet Association still will play a crucial role, filing legal arguments in the coming case. And in formally participating, tech giants will have the right to appeal a judge's decision later if Silicon Valley comes out on the losing end. "The final version of Chairman Pai's rule, as expected, dismantles popular net neutrality protections for consumers," said the group's chief, Michael Beckerman, in a statement. "This rule defies the will of a bipartisan majority of Americans and fails to preserve a free and open internet."
