A lot of people dislike it for the privacy nightmare that it is and feel the threat of an EEE attack. This will also probably not be the last time that a big corporation will insert itself in the Fediverse.
However, 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?
There’s a bit more to it, but essentially yes. For example, beehaw.org has defederated from lemmy.world, but we can still view their content. We can interact with their content and reply to their posts, and other instances that they are federated with can see what we do there, but beehaw users can’t see any of it. Basically federation is a one-way street. You can federate with an instance, but they don’t have to federate back.
That’s kind of the motto of the fediverse in general. It’s supposed to be de-centralized and de-corporatized. There are no built-in features for advertising, for example. It’s meant to be a place that is safe from the things that we’re afraid Facebook is trying to do. Overall, it mostly is. They can attract people out of the fediverse and into their garden which they plan to wall off, but they can’t quite shut down the independant instances.
