decentralize it so that the crazy alt-right trolls and q-anon wackjobs and jan-6th sympathizers etc etc can join the blue bird and feel happy and the rest of us left-of-center folks can carry on nerding out on tech and keeping a more or less inclusive ecosystem.
edit: in this way (and perhaps maybe mastadon already does this) the two need not see the same stuff in their timelines and the media can still consume from twitter to make their headlines. It might not stop the next Trump presidency (it was clear to me he used twitter to help win office) but at least the service will stay more or less the same for those that want it to and those kicked off can come back to shout into the wind and those that support them can cheer but the rest of us won't have to see it.
