Funny the thing about the whole short essay thing, because I basically only wrote "I wanna try Lemmy and I want an active instance where I can be active in"
Beehaw didn't left the fediverse, it defederated from two Lemmy instances over the more than 20000 that exist in all the fediverse. The number of instances that Beehaw defederates from (which, of course, is bigger than two, as there are intances that are globally defederated) is tiny in comparison with the size of the whole ActibityPub -based fediverse.
Make sure you understand how the fediverse work before resorting to lying.
