Which are that the government can't censor speech. Forcing a private entity to support any form of speech is actually against the first amendment, it is compelled speech.
Who's forcing what? They are just inspired by it, at least that's what the comment you are replying to is saying. If a private corporation wants to support or enable free speech, they are allowed to, just like you said. This is literally from Facebook itself so I'm not sure who is compelling who.
Meta, as a large and powerful entity with the ability to censor as much or more than many governments, is opting to allow free speech on its platforms. So is X. That spirit is inspired by the Bill of Rights, not Elon Musk.
