@blaine I don't know. They are saying that they're planning to support migrating your followers out of Threads, and I would guess that'll be via the `move` activity since that's how it's generally done on the fediverse. So it kinda seems like they're already doing this?
I do think you're right that it needs legislation though. There's a part of me that feels like they're only doing this because the DMA is about to require them to in Europe anyway.
@jfred it may be that they're trying to preempt more antitrust legislation; either way they'll be able to leverage all this, so hopefully they follow through.
