What does defederating from Meta's Threads.net actually accomplish? - Lemmy.one

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 [http://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?

Meta are performing what is called an EEE attack (Embrace, Extend, Extinguish). Basically, it involves a larger corporation creating a thing that hooks into an open standard, artificially inflating it, slowly adding new, proprietary closed-source features that other members of the open standard cannot use, and eventually removing support for the open standard entirely, forcing other users to enter their walled garden because that's where all the people are. https://en.wikipedia.org/wiki/Embrace,_extend,_and_extinguish

While I wish ActivityPub was GPLv3, it is at least under the MPL, and they are going to have a hard time introducing proprietary closed-source features on a communication platform that requires them to share the source code.
