By extension, this is why I don’t think defederating with Meta is an effective strategy. Like gourmet burger restaurants refusing to be on the same block as McDonalds.

It’s not a question of whether fediverse and Meta get defederated, it’s a question of when. Even if we don’t defederate with them the history teaches us that eventually, when they get a monopoly on the content and users here, they’re gonna shut down the rest. It seems the only choice is whether we want to do it while meta is still growing, or wait until it becomes strong (or hope it falls apart and dies).
