I think right now everyone wants to join beehaw because its big. Beehaw doesn't want to be big, it wants to be safe for its users and as a result defederated a ton of instances to maintain it. you're not missing anything by leaving beehaw behind. It's a blip on the radar in these early days. Yesterday i was kinda mad about it too, today I have just moved on and guess what...it's fine. I guess they plan on refederating at some point with lemme world and shitjustworks but for now, they are maintaining their community as they see best. I don't think it will work long term because as people get acquainted with what it actually means to defederate and how it creates an echo chamber (many don't yet understand how visibility of comments works on defederated lemmys), people on the outside will stop wanting in and people on the inside won't even realize how bubbled they have become.
