Every "permaban" like this is an opportunity to get a famous person on a distributed Twitter competitor like GNU Social (especially if the ban actually lasts). If you work on one you may want to contact him. People whose presence is objectionable to Twitter are the natural early adopters for distributed social networks.
Except GNU has a Code of Conduct talking about considerate and respectful.
Whatever you think of COCs, they might be hard to take seriously if it's "be considerate or respectful, unless you have both a large following and were kicked off Twitter for what largely amounts to abusive and hate-speech like behavior, then we'll actively court you to come to our network!"
