Just an FYI for the RSS thing: if a Bluesky account is set to be viewable to logged-in users only, its RSS feed will not work. It only works if the profile is viewable publicly without logging in.

What’s the number of Threads users compared to Lemmy? If the number of Threads users greatly outweigh the number of Lemmy users, then we’d simply be drowned out by all the Threads posts. That’s part one of Embrace, Extend, Extinguish.

Extend adds functionality to Threads that Lemmy either can’t support or won’t support for a while due to development time. People migrate to Threads because Lemmy is “missing” functionality. Plus, though I’m not clear on the exact legal specifications, proprietary code can be added to open-source code, and the proprietary code would be copyrighted. In other words, Lemmy devs would have to figure out a way to interact with and mimic Threads’ proprietary code using open-source code.

Extinguish is when Threads’ support of Lemmy is eventually dropped. The users left on Lemmy have suddenly lost a huge amount of content, and they’re left with fewer users than before Threads enabled federation.

I actually don’t have a problem tying everything together. I think the fact that Mastodon and Lemmy can communicate with each other (even though it’s not really intentionally designed that way) is pretty neat.

What I do have a problem with is the corporations that are trying to do it. I don’t trust any corporation to do it responsibly, especially not Facebook.

You’ve basically got it. To use the “Google XMPP” example some others have:

XMPP users existed, and its userbase was growing (similar to Lemmy). Google made Google Talk, a desktop chat application they used to have, compatible with XMPP (which was the “ActivityPub” of chat applications) (embrace).

After a bit, Google started adding their own proprietary stuff to XMPP. (It’s similar to how Apple/ Google added proprietary stuff in their respective text message applications, like reacting to a text with an emote.) The XMPP devs, for whatever reason, couldn’t or didn’t make Google’s own proprietary Google Talk features compatible with XMPP, so XMPP users might’ve started feeling left out (extend).

After a while, Google Talk got rid of its XMPP support, and, as a result, many XMPP users could no longer communicate with many of the friends they had made on the platform. (Since Google Talk users outnumbered XMPP users, there was a very high chance that people you communicated with on there were using Google Talk.) Google Talk users, on the other hand, simply noticed maybe one or two people on their list had gone offline permanently (extinguish).

But they would still be unable to embrace (and, by extension, extend and extinguish) because users from Threads would be unable to interact with users from other instances. Basically, they’d be unable to get rid of a potential competitor using the EEE method.
