If you care about this and have the time, just start grabbing links from hexbear or reddit or your bookmarks and post them to appropriate non-beehaw communities.
Beehaw is a large, active, “no tankies allowed” lemmy instance that has suspiciously defederated from much of the rest of the fediverse, including its largest competitors lemmy.world and sh.itjust.works.
This potentially threatens the lemmyverse as a system. If Beehaw gains a critical mass of the active lemmy userbase, and continues to defederate from its competitors, it could cause a vicious cycle where everyone goes to Beehaw because “that’s where everyone is.” Alternatively, Beehaw could use the threat of defederation to backseat-moderate other instances and enforce Beehaw politics outside of Beehaw. Either way, federation is defeated if Beehaw gets big enough.
*Lemmy.world is like twice as active as beehaw rn, I think beehaw fucked themselves over with their vetting process
"Match our content rules or we will defederate with you!!!"
"Go right ahead! We literally don't care! You won't be missed at all! Wtf, are they even real, lmao"
This is kind of a major point behind the concept of the fediverse: that you can have your own rules and nobody else can enforce theirs on your space...
