Net Neutrality Fight Missing FANGs

Why are the big tech companies (Facebook, Amazon, NetFlix, Google, etc) silent on the current attack on Net Neutrality? Net Neutrality is clearly a good thing for everyone, so why o why are these companies backing off the fight?

Does participation in the Internet Association give the big tech companies a pass on standing up to bad policies coming out of Washington?

Why are they afraid of Washington these days? Or are they afraid of the giant telecom companies that control the pipes and access points?

I just think its totally weird the way the big guys went quiet on this extremely important issue.
