Free speech means that you can't be put in jail for something you say. That's it.
But nobody has an entitlement to be amplified. That's not a right. Nobody has the right to unfettered access to someone else's platform. That's never, ever been the case. You never had the right to edit the front page of a newspaper that you don't own, you don't have the right to set up a platform in the middle of some company's office to talk about your crazy ass theory, and you don't have the right to spew malicious, bad-faith shit into a twitter thread.
