And that’s what I’m questioning. Would you? Would you think others here would? I wouldn’t. I’d rather go to whatever fork Fediverse devs favor instead. If anything, all the fear being expressed every time Threads integration is brought up only emphasizes that this is not how it would play out

The network effect can be strong. Say you're now able to contact all your friends via your favourite Activitypub instance, you had to previously use Facebook.com or Threads or whatever but now they're all here. You delete your Facebook and keep your Activitypub account to speak to all your friends who are on Threads.

Now Meta pulls the federation plug, or adds some feature that makes your Activitypub server not able to fully cooperate (Maybe you can talk, but you can't video call anymore, or you can't post GIF/images, whatever). Now what? All your friends are over there and getting annoyed with you. So... you eventually succumb and fire up a Threads account.
