I don’t think there should be one plan. Some people on the Fediverse want nothing to do with Threads. Others want the massive userbase because that’s the only way to get the content and discussion they’re looking for. Instances which do federate will have to deal with moderation issues, and will choose different ways to do that.
The beauty of the Fediverse is that there will be instances with policies to suit every user. Exactly as it should be.
