@amandapalmer using federated (like email, or the telephone system) and open source software (free, supported by patronage, like modern music) is a good move.

Just make sure you understand and agree with the rules for the server you are on (each is different, but it's not too hard to move).

Funny thing is, it seems like Musk wants to make Twitter open source and maybe better interconnected, e.g. put the power back into individual hands on who they ban (rather than being dictated from the top), although the reaction is certainly accelerating that.
