There’s no way they see it as a threat.

So why they are expending dev time to partially integrate with activepub? What they earn? Cause this would not make them a dime, not in short term, and even less in long term.

Ahmm, lemmy.world is already federated with mastodon as well, fediverse is one network of federated instances, it is not one for mastodon and another for lemmy. You can interact with mastodon post already from here

Maybe but idk if they cannot just evade it juridically since technically Threads is another company besides being owned by Meta, also they will just ip block EU users. Don’t get me wrong, I would love to see Meta being fined, I just cant see this easily happening.

But if your company is not localized in EU how they will prosecute the company?
