Idk. I feel like the fediverse was always destined to be various walled gardens with like a few common hubs that connect them. The issue is that .world took the exrta step of blocking their ability to see our comments. Its not due to being defederated i think they did something else to not see us even on instances we are both on.

Its kinda funny. Ive seen a few .world tech support posts and been like “Oh… i could help but u wont see me” lol.
