Do what you feel you need to do. Beehaw was my first Lemmy instance, although I have since left. What I initially liked about it was that there was active moderation and the admins seemed to do a good job keeping things running. It was a chill place that didn’t really appeal to the more toxic types you run into on the internet. It was like a friendly little bubble and a good home base in the fediverse.
While I appreciated that toxic instances were blocked, I felt blocking instances simply because they didn’t have great moderation was a little too much. It meant I was missing out on a lot of good content too. I understand the decision but I realized then that the original Beehaw community was more content to be insulated than I was. For a lot of people there, it was more important to have their own tight community than to be part of the fediverse. There’s no hard feelings about it. I enjoyed my time on Beehaw and contributed to server costs. I found another good instance that’s better federated and manages not to have a bunch of nazi and racist garbage so it’s all good.
These conversations have been brewing for a while at Beehaw. I would imagine a lot of the people who don’t especially like the insulated approach have moved on to other instances or created alt accounts for when they want to interact with the larger fediverse.
I don’t think anyone will miss anything if Beehaw migrates to a non-federated platform.
