Preventing enshittification of platforms rests on credible exit for users and devs. #ActivityPub and #SMTP are not perfect but

a) are implemented und understood by many players,

b) enable freedom of choice of servers and clients,

c) implement #RightToMigrate as well as self/community custody

Many #p2p projects promise to remove servers but often promote and depend on a single implementation stack, have no spec and no interop among #p2p islands, and thus struggle to provide credible exit.
