I hate this little thought terminating cliche. It's trying to make everything into hypocrisy which it isn't. Say he banned everyone who ever said anything pro Israel...you can fairly apply that rule across all people, and have disparate impacts.
The problem isn't that he's censoring others but not himself, it's that the rule itself is bad on its face.
This is hypocrisy. He called himself a "free speech absolutist" after he bought Twitter. He called it the "digital town square." Ever since then, he's banned anyone who says things he doesn't like and keeps the Nazis. He's absolutely a hypocrite and he should be called out on it.
If that is what they said, it would be hypocrisy. The cliche is "X for thee and not for me" so the claimed hypocrisy is that he is censoring others and not himself for saying the same things. That isn't the issue, as you point out the issue is that he is censoring when he said he wouldn't.
