So it’s closed source Mastodon?
I don't expect it to stay closed source. But there are significant differences to Mastodon. Just to give one example: Mastodon server admins actually can read your private messages. Also Blue Sky's approach to data portability and how to implement filtering/indexing is more developed. It might be personal preference, but I prefer AT Protocol's approach where the servers have less powers, and the users have more power…
Microblogging shouldn't have private messages. Let people have a profile and a link to an email address or similar and be done with it.
I'm not sure why a service designed to publicize things so that everyone can see them ALSO chooses to take on "private messages." I get that's how the big money incumbents see it, but I feel like less would be more here.
