You are a conspiracy nut, Mr Adams. Twitter is a private company. Repeat: Twitter is a private company. It's not even nominally working in your name (like a democratic government is). The First Amendment says nothing about private entities. Just because every TV news show uses it as a lazy source of react quotes does not make it a neutral public service.
Again, twitter is not a public service. Twitter owes you nothing; you haven't paid it fees/taxes. It's also a terrible place to discuss nuanced concepts (which is most concepts). Twitter is also not the only place you can express yourself.
The more I read of Scott Adams' recent murmurings, the more respect I lose for him.
