The leading lobbying group for Amazon, Facebook, Google and other tech giants is joining the legal battle to restore net neutrality

The Internet Association, a leading lobbying group for Amazon, Facebook, Google, Netflix, Twitter and other tech giants, said that it would be joining the coming legal crusade to restore the US government’s network neutrality rules. The 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.

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 FCC Chairman Ajit Pai’s decision. 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.
