Why do they want to step into what we are doing here?
I think there’s a much simpler explanation. Elon’s actions are causing users to want to leave the platform. Meta wants to pounce on this opportunity. ActivityPub is an established, open source protocol that allows Meta to quickly spin up a Twitter competitor. The federated nature means that Meta can reduce regulatory risk. At the same time, they can lobby for increased scrutiny of Twitter since it isn’t interroperable like Threads.
I have no idea if this is actually how Meta is strategizing. But what I definitely know is that Meta absolutely doesn’t consider federated social media a threat. They aren’t trying to squash us. They’re aimed at Twitter. If they make some change that degrades the experience for us, absolutely we should consider defederation. Until then, let’s try to make some converts out of Threads users.
