But in general I don't think you can compare broadcast mediums to bidirectional ones (e.g. words on the telephone or text on the internet).
They’ll write the rules together, make the barriers to entry even higher, and pat each other on the back.
Then it’s on to the next moral panic, this one’s been fixed!
The US government hasn't censor broadcast media much given that most broadcast media owned by large corporations with ties to the state themselves.
And there's no reason that government wading into regulating Facebook could do anything remotely sane. A lot of Facebook's scandals have nothing to do with censorship and everything to do with filtering bias. When state agency is going to be qualified to regulate that?
You won't want a random foreign government censor your speech.
I'm not sure this has to be an all or nothing thing. We have some reasonable protections built into the Constitution and case law that back that up.
I understand your hesitation about having the government involved as there are plenty of examples of government influence on the media around the world. I share the same fears.
With that said, do we really have any real world proof that the US government in recent years has over stepped its boundaries in regards to media restrictions?
