I think you’re mixing up the people that take part on thread of communities hosted on Beehaw (who belong to hundreds of servers, both in and outside of Lemmy, not only to Beehaw) and the registered members of Beehaw as an instance. I’m talking about users registered at Beehaw.

Beehaw has the largest communities because people aren’t creating communities on their instances, instead recurring to Beehaw-based communities. But there’s a difference between participating in Beehaw-hosted communities and being part of Beehaw as a instance, a register user of Beehaw. This is not the responsibility of Beehaw, which is closed to new community creation. Federated social media is made by its users and here users have the opportunity, the possibility, and the ability to diversify Lemmy and the bigger fediverse by creating communities in other instances and participating in the communities that already exist in other instances.

Beehaw as a instance aims to be a nice and safe space, and as such attracts marginalised people to register into it. Yes, there are people that are registering in Beehaw without even reading what the instances is about, only because it’s a big instances. These are the people that are now “feeling betrayed” or “unable to understand” why Beehaw is defederating from instances that allow trolling. They chose a community that wasn’t the best for them, but I don’t put them as fault because, just like it happened with the twitter migration, people are being suggested the larger instances and aren’t being explained that being on a smaller instance also allows you to federate, sometimes way better than in larger ones that are often blocked/muted/defederated by small(er) instances for simply getting too large.
