Threads is testing federation for a few selected profiles. I assume they also have some kind of whitelist of instances or software, because out of the 8 instances i have accounts on, federation with threads only works on lorsh/mastodon. Or maybe it's just buggy at the moment.

It's still a huge step forward. Now if you have a normie friend who whines about elon's bad decisions but says fedi is too complicated when you suggest it as an alternative, IT'S YOUR DUTY to call them a lazy retard 🙂
