Yes, the point of the Fediverse is that everyone is free to associate with groups they choose. There is nothing wrong with creating instances that are very isolated. What Beehaw wants with the “improving moderation tooling”, however, is a safe space where the network is restricted from them, but they still have full access to the rest of the network. That suggestion is what I was calling selfish, because this way their users would be parasiting off the content and moderation of other instances while giving nothing back.
