They want to build a walled garden. They've defederated 400+ instances. This extreme desire for control is what made me leave beehaw for lemmy.world and I'm not looking back.

I wholeheartedly support NOT engaging with beehaw. Any instance that supports defederation and censorship is an instance NOT worth supporting. The fediverse is supposed to be a refuge of free speech (within reason of course.) If an instance chose to defederate and isolate itself, it deserves the very same isolation it so wanted.

Tldr; beehaw wants to isolate, then give it the isolation it wants.
