I think Google, FB, Twitter, etc., only do what the Federal Gov tells them to do.
I don’t think they institute these policies on their own. On their own, they don’t care.
They do what they are told and they talk the talk behind the policies in support.
“They are a tool of the government....”
“That’s right folks, don’t touch that dial...”
Or, perhaps they do what their CCP paymasters tell them. Same for much of the FedGov.
