Most of them have lied under oath before congress, have meddled in state elections, have presented themselves as clear and evident dangers to the public by their constant and rapacious attacks on their users' privacy.
Lying in furtherance of The Right Side of History(tm) is a good thing. Meddling in elections in support of the "correct" candidates is a good thing. Being a clear and evident danger is fine as long as you're not a danger to the Party. And as long as they keep handing over all that data when asked the privacy violations are exactly what the government wants.
Why would they want to go after some of their best allies?
