I had a few late night conversations with the Bluesky devs last year at dweb. As others have mentioned, they care a lot about being able to move your entire account. It’s also very important to them that people can have millions of followers, and have the platform still perform well at that scale. That’s not an easy thing to do. I can’t remember the details, but I’m pretty sure activitypub is missing a bunch of core technical capabilities that they needed to make it work well. They’re certainly aware of activitypub. Christina (the author of activitypub) was at dweb too giving talks on Scheme and whatever her latest mad science was that year.
