And if Meta tries to pull some sort of destructive shenanigans, sure, then defederate from them. Not because they're Meta, but because they're pulling destructive shenanigans. There's already plenty of instances that get defederated for that sort of thing.

In principle, I agree.

My fear is that the fediverse has no big hitter that can compete with Meta’s resources. The closest thing would be Mastodon.social, and they are still tiny compared to the two-billion instagram users Meta is gonna advertise Threads to and the 390 million ~~Twitter~~ X users that they are trying to poach.

I think Meta will play nice in the beginning, but eventually (perhaps even quickly) will gain a much larger userbase than everyone else. From there, it is only a matter of time before their users create more communities and content than everyone else.

Eventually, anyone who is federated with Threads is going to get accustomed to seeing and enjoying Threads content (why wouldn’t they? It’s from people.) That is where I fear Meta will start to flex their muscles because at the end of the day their business model is based on selling user data to advertisers; having users being able to interact from other platforms doesn’t really fit into that as well as having everyone be on your platform.

Obviously, I don’t have a crystal ball and all of this is theoretical, but I can see something like this happening where people start to abandon smaller platforms for Threads because their preferred platform got defederated.
