Because Beehaw is not the entirety of the federation? I am not sure if I follow your question. I am not on Beehaw.
I support the exploration of federation concept (which at this point, the tool and experience are not yet developed to that point), and support the people and communities going through the transition from reddit to this deferation system (which a very small percentage of people went through to here).
Beehaw supports neither of these. They backed out, and they want to create curated communities specifically.
My energy is spend on the many communities I do engage with... on reddit. Those communities have barely any post here because the majority of people do not trust these platforms. It makes sense that I want the federation as a whole (ignoring beehaw) to not sink before the people can move to these spaces.
