We really need to start asking ourselves what a "future-proof" social media could or should actually look like.
Does any media company actually think about it? I know there are some big tech ideas like Meta or whatever but I'm serious, it feels like no one running anything has any real thoughts about the future except for in terms of propaganda or advertising. No one actually cares about the social part of social media which is why people have to build it on their own... Hence, the fediverse.
I think that begging the mods for refederation will be a common occurrence in the newly emerging fediverse, but I think we'll all just have to get used to the idea that the fediverse is about voluntary communities and you'll have to forge your own path using multiple accounts/etc. The entire point of defederation is that Beehaw doesn't want certain communities or people with certain viewpoints congregating here - that's the choice of this community and the use of multiple accounts does get around that but it's just what will have to be done if you want to be someone associated with defederated communities.
