There is one big reason why they would care - antitrust and EU regulation protection. They have no intention to destroy the platform Rather they want to please the regulators as they are leveraging the open standards. The EEE strategy is a conspiracy theory. Government regulations are the most probable reason for this change.

If something killed XMPP for me - it was Matrix. On open source replacement that is not only more popular, but has more active development and it’s easier to use. No big company required. And since XMPP is still alive for its niche user base and EU is probably the reason for Threads federation - I don’t think this is the right hill to die on.

I am on lemmy.zip and had no problems so far. I really don’t have anything more to say.

Yeah, I am using Infinity for Lemmy and I can confirm this option does work!
