This will die down eventually: at the moment there are many different independent ideas of how to build federated reddit alternatives that have yet to really be tested for how the underlying systems and moderation tools scale. In due time there's going to be a standard application or at least standard exchange format between the different services, that just doesn't happen right now since all methods are really new and now get "suprise load tested".

That's also why you experience outages and Beehaw explicitly asking people not to join: everything went from "fringe techdemo" to "the internet is moving off of reddit" in a matter of less than a week (same thing is true with app support) and everything is at its breaking point: from the underlying technology to new communities appearing in a matter of hours to days (usually with less experienced moderators).
