I don’t believe the EEE narrative about Threads federation. The number of #fediverse citizens isn’t large enough to justify the (substantial) investment in Fedi/Masto/ActivityPub interop if the goal is just to bring them to Meta. @mosseri explicitly said that the goal was to enable people to move off Threads and I believe him, because…
…All the Big Techs are under considerable political pressure to be less lockin-y and more interoperable. Especially in the EU. If any Threads user is free to step over to some Masto/Akkoma/whatever instance, it’s hard for any regulatory agency or politician to make a case that Meta is locking people in.
