I’m confused about this federation discussion. Please @stux @mookie and other #fedigods help me understand:
1. I can follow @potus@threads
2. I can reply to people at @threads
3. People on @threads cannot follow me (because something prevents them on their end)

Isn’t it just as planned? If these statements are true i would be super happy and jolly and merry for the rest of the day
