What this post is asking for is exactly not that, that if you are in any instance that federates threads, then you shouldnt be able to interact with any that follows this posts petition

I must genuinely ask? What does this accomplish, a lot of instances being split apart because one federates with meta and the other doesnt, its not like the meta posts are gonna make it to your instance if you defederate meta, so you are really just splitting the community over nothing. Privacy wise, activity pub is public, by design, so they can just already pull all the information it exposes, and likely do. And finally? How does this stop EEE?
