None of the services you listed provide a platform to spread information though. Freedom of speech means I recognize your right to say something. Doesn’t mean I have to allow it on my platform if I don’t agree with it or think it’s a problem. I could find no information about Facebook taking government money at any point but even if they had that wouldn’t make them part of the government. They can ban whoever they want, I can think of a few people on the left that spread false info to.
