What made you pick the Lemmy server you are on?
Does it actually matter?
Lemmy.ml and lemmygrad as well as tech.de (or something similar) I might host myself sometime later. I was on mastodont a while before , went back and tired of proprietary again. This time I am thoroughly fed up and will stay.
For me federation is good. I see the problem with filterbubbles but I'm to old for this shit. I rather be in my bubble.
