Polyproto is a really exciting one I’m keeping an eye on, though it’s still very early in development. It’s a protocol that allows for migrating accounts like you mentioned since the user owns their own identity. AFAIK only a chat app is being worked on right now, but the protocol allows for extensions and I don’t see any reason it wouldn’t work for other social media
I’m upvoting this because it made me laugh and I’m 90% sure you’re joking, but I think other people may be less sure and you might wanna add a /s lol
