A lot of people dislike it for the privacy nightmare that it is and the threat of an EEE attack. This will probably not be the last time that a big corporation will insert itself in the Fediverse.
People also say that it will help get ActivityPub and the Fediverse go more mainstream and say that corporations don’t have that much influence on the Fediverse since people are in control of their own servers.
What a lot of posts have in common is that they want some kind of action to be taken, whether it’d be mass defederating from Threads, or accept them in some way that does not harm the Fediverse as much.
What actions can we take to deal with Threads?
Then they will either threaten to defederate with that instance unless they impose the same rules they have or tell that instances moderates to punish you. Once the instances become intertwined enough, their rules become ours rules or they’ll threaten to defederate essentially kill that smaller instance.
There simply isn’t a world where Meta allows Threads users to see content that they don’t want them to see on their platform. I’m sure part of the reason they haven’t federated yet is so they can figure out a way to hide shit from other instance on their own instance.
