Will Meta embrace-extend-extinguish the ActivityPub protocol?
There are comparisons to be made between Meta adopting ActivityPub for its new social media platform and Meta adopting XMPP for its Messenger service a decade ago. There was a time when users of Facebook and users of Google Talk were able to chat with each other and with people from self-hosted XMPP servers, before each platform was locked down into the silos we know today. What would stop that from repeating? Well, even if Threads abandoned ActivityPub down the line, where we would end up is exactly where we are now. XMPP did not exist on its own outside of nerd circles, while ActivityPub enjoys the support and brand recognition of Mastodon.
