The government however could come in and simply make it that you have freedom of speech on social media. So if Twitter bans someone for saying "a man cannot be a woman" that person can sue them.
The democrats will NOT do this however, the current censorship on social media is benefiting the left-wing.
Do you believe the US government has the ability to simply prohibit speech by corporate entities? Is it in accordance with free speech principles for a federal government to prohibit certain types of speech?
Personally I see this as something that will come eventually. However, I don't think that's what Twitter should do.
My idea is that twitter should act more like the united nations. You create a 'diplomatic immunity' type of account that people can request. It can be something like:
Minimum 50,000 followers.
Account history of 1 year.
If approved you can no longer edit or delete your posts; but you also cant be kicked off twitter or other be harmed by rules of twitter.
this by itself will solve the problem that twitter has.
What does this mean? Mark Zuckerberg, Jack Dorsey, Jeff Bezos, et al already have their constitutionally protected speech, except for where their roles as executives at public companies restrict them. If they find those restrictions onerous they can leave their roles.
