Is the activitypub compatibility confirmed?

There was a Mastodon thread by someone who had decompiled the leaked Android APK for Threads the other day. There were a few strings in there talking about the fediverse and federation with other servers, so it seems like they at least planned to add it at some point.

Not officially, but it’s about as unofficially confirmed as it’s possible to be. Though I have no idea if it’ll be available at launch.
