This is why I’m in favor of not having await and see policy toward Threads. The safest thing to do is assume they’re lying.
Threads users aren’t Fediverse users. Meta isn’t another instance. Even former Meta employees should be treated with extreme suspicion for years if they try to defect.
Nobody who’s ever worked for “Big Social” should be allowed to touch the ActivityPub standard. It should be obvious that their livelihood goes against what it stands for.
