What is ActivityPub and why Threads now?

ActivityPub's the fediverse glue — protocol for servers talking posts, likes, follows. Threads added it April '24 for outbound federation. PR win, regulatory dodge.

Will Bluesky's AT Protocol kill ActivityPub?

Nope. It'll coexist, like RSS/Atom. Bluesky wants IETF nod for legitimacy, but adoption's iffy. Dual worlds ahead.

Does social media interoperability free users?

Kinda. Portability yes, but lock-in lingers via habits, algos. True freedom? Needs identity standards too — we're miles off.
