Why wouldn’t they be able to interact with it. The way I understand, if I defederate with them on my instance they can still see my content but I can’t see theirs. There’s nothing stopping Metta from taking that public data anyways and allow only their users to interact with it in their own sealed space. With how many users they have, it’s possible it wouldn’t even be noticed by the average threads user
Well, theoretically we could do the same. Host shadow-Threads content. That’s essentially what’s going on with reddit repost-bots, after all. But if you look at those they usually have no comments and for Facebook in particular, I would argue that enabling their ability to spread their content to the Fediverse is dangerous even if we don’t interact with it.
And the same is true for Threads - they could actually do that kind of re-posting, in theory, but then it’s pretty much just them reposting a link to some post on the Fediverse with their own silo. We wouldn’t see any of them at that point. I’m arguing for defederating on the basis that it protects us from Meta/Facebook, not on the basis that it would stop Threads users from seeing some parts of Fediverse content (essentially posted as links) ^.^.
