@ricard they now allow "replies".
I put it in quotes because it's not how Fediverse does replies, aka not how replies work on every other platform.
1. It has to reply to a post that already exists on Threads. You can't just make a post and tag someone if it's not replying.
2. You cannot mention more than one user.
3. The reply is private on Threads, only the mentioned user will be able to see it.
They know it's not right and did it anyway. I replied to a devs post about it where they didn't mention these flaws and they liked my comment.🤦♂️
I'm VERY skeptical that they'll ever federate fully like they should. It's a marketing tactic to gain users and then eventually they'll say "it doesn't look like Fediverse is what people want right now" and turn it off...
