The only “creepy” thing about it is that viewing who upvoted/downvoted what isn’t a feature that’s just built into Lemmy (and Lemmy-UI). I can’t imagine why the authors of Lemmy would want to have a class system with some (instance admins) being able to see vote information and others (everyone else) being unable.

You say “we all know our votes here are public record”, but that’s not really true. Even Lemvotes doesn’t work for at least half of the posts I’ve tried it on. It’d be more accurate to say “we all know our votes here aren’t secret”.
