In the context of moving the goalposts, you are asking other commenters to justify another person's actions that are increasingly at odds with their words.
I personally think that the narrative you are interrogating is weak, even a straw man version of the people you think you're arguing with. It seems clear to me that Elon has long operated on personal grievance with respect to Twitter, and that "free speech" is just the veneer he puts on because it works.
