Federation is a feature. If you want to spin up a network of Lemmy instances between universities and ONLY federate with other universities, you could!
Want to spin up a private instance for you and your friends and not federate with anyone? You can do that too!
To me one of the big selling points of federated services is you don't have to be part of the same giant bucket as every other shithead. If you want, you can pick and choose who you federate with.
Beehaw never tried to promote itself as a default instance. It was a toy hobby project started by four friends that through a fluke of where it was listed, had an enormous, unexpected growth spurt.
It's still those four people's server though, and it's totally their prerogative in how they run it. We aren't entitled to it's content, and users don't have to stick around if they don't like the way it's being run.
The fedeverse gives you choice. That means there will be some servers whose choices you don't agree with.
