they dont qualify

You know that. I know that. The courts don't know that.

As far as the law is concerned they're operating with immunity. Unless some miracle happens with Texas and a free speech challenge is issued (which is highly unlikely) they will continue to operate with impunity. Their censorship record needs to be proven, which so far hasn't happened. One employee or even a single building full of them, have continuously used variants of the "this team of employees was given orders by their manager who was acting in their personal biased judgement unrelated to normal orders given by the company." and other legalese bullshit to avoid admitting fault.

they have regulatory capture

and while that has protected them from most of it, other agencies still exist in areas the corporations have yet to take over. Altering 230 by going through the courts outside of their control would be easier then trying to prove criminality.

They have corrupted the government.

Part of it, but they're not the illuminati.
