Only if Threads is open source, but it doesn’t seem to be.

their data will (maybe) be available, but as far as actual features threads is a whole different thing

think of it like kbin and lemmy: we can interact between them, but if lemmy adds a feature kbin doesn’t get it

so if threads adds a feature, mastodon and the rest of the fediverse doesn’t automatically get it

actually pinned posts i think is a good example for kbin and lemmy: they both have pinned posts, but they’re slightly different and therefor don’t operate correctly together
