You're framing it as if this is a bad thing that Lemmy can only see some of the agupe content, but wait until you see how much content non federated platforms can see from each other! I really don't see how some content is worse than none, if you really want all of it then make an account over there like every other social network in the past requires you to browse on their site/app. It'll probably improve over time but it really sounds like you're upset that it already sometimes works instead of not at all.
