It's interesting that many are debating the value of this 'rule', when this action is blatant abuse of his powers to silence his critics. He has now a lengthy and growing history of this type of behavior, so it was 100% foreseeable. He could just come out and say that its his twitter and he can do what he wants, but no, because he also wants to be seen as a 'defender of free speech'. He acts like a-hole, but then expects unquestioning adoration.

I wish that were true, but I think at this point it's technically mutable but ossified, much like the Bitcoin genesis block. You could change it, but you'd have to do a lot of work. So much work that it's just not gonna happen.
