It's getting pretty tiring to see people feeling entitled to have access to any and all communities of the Fediverse, if the people paying for the running cost of the Beehaw instance wants to defederate (for whatever reason, "good" or "bad"), that's their prerogative.
If you really want access to their content, apply to join, otherwise sign up to any of the dozens of lemmy instances federated to the rest of the fediverse.
One of the great things about the Fediverse in general is choice, user and instance admin can choose how they want to interact, and are not beholden to a company or group which can take any arbitrary decisions they want.
TLDR : Instance admin are entitled to how they want to run it, you're not.
To the people shitting on the idea of a default defederation with Meta, how about we deferedate not because it will affect us as posters but because they are evil pieces of shit?
