Afaik, whenever an Activitypub instance has defederated from another it has always had to do with some combination of bad user behavior, poor moderation, and/or spam. Are the various instance admins who have decided to preemptively block threads.net simply convinced that these traits will be inevitable with it? Is it more of a symbolic move, because we all hate Meta? Or is the idea to just maintain a barrier (albeit a porous one) between us and the part of the Internet inhabited by our chuddy relatives?
(For my part, I’m working on setting up my own Lemmy and/or Pixelfed instance(s) and I do not currently intend to defederate.)
Defederating from Meta changes nothing in this regard.
They can take. That doesn’t mean we need be ok with giving. Just because they’re ok with theft IP doesn’t mean we need to be ok with them doing it.
What “IP theft”? By using a service built on ActivityPub you are inherently and deliberately broadcasting your posts to the public. Meta has just as much right to read those posts as I do.
