With the Christian's banning books in the US, I'm not worried about limiting Christian hate-speech. Right now, that is the main problem. The Christian majority hasn't hesitated to ban and censor content they don't like, and kill those they deem problematic. Fascism is the immediate threat to everyone, everywhere.

This just looks like right-wing paranoia to me. The first amendment says nothing whatsoever about a private enterprise’s responsibilities toward free speech - only the government’s.

If the government has a legitimate interest it may be to keep private enterprise from becoming a monopoly in the first place. A great solution would be to launch a public utility to compete with those privately owned power centers, then the first amendment could apply.
