There's two different sorts of "you" here. There's the big platform of "you" that AWS shut down, that was shut down for the not-allowed-in-public-sphere speech.

Then there are the "you"s that are posting on individual platforms that get to choose their own standards of conduct. AWS stopped business with a platform that would not be allowed in the public square.

An individual that got banned for dead naming can just start another account anonymously, as far as I know.
