A potential federation with Threads (should Thread decide to implement it) would overwhelm Lemmy/Mbin/Piefed with millions of users (compared to the 40k monthly current active users), transforming those platforms into a threaded version of Facebook
Addendum: Yes we know that you think ml/hexbear/grad are tankies and or .world are a bunch of liberals but it gets old quickly. Try and come up with new material.
Question if that's possible, especially if they really start a search engine, but yeah at least do not hand over the data on a golden plate
