All of the examples I have seen, when have a response by Twitter associated with them, is that Twitter follows a 3 strikes and you're out rule - and they apply these rules to everyone. If there are a few examples where this isn't followed then okay, there were mistakes, problems - but that is then at a government level that needs some judiciary process for.

Re: 'so many examples of people getting banned for "wrong think"'- have your sources been confirmed/provided confirmation by Twitter that's that what it was - and

Moderation (parenting) is a very important and effort full work that is required to prevent a wild west of society. A wild west of society is more costly and leads to far more suffering than a managed home; if you want to raise children that are racist within your own home, or who where you find it acceptable for them threaten to kill others, you're allowed to - however forcing ALL platforms to allow all behaviour is insanity, and so Twitter needs to be allowed to have the rules they want to allow - and people can "vote" by using that service or not, and then other platforms can have their own rules - and that government as a whole will have to decide what those bounds are; perhaps should government provide a free speech platform like exist public parks as an option that everyone has available to them.
