Not having downvotes at all makes the exact reason I dont like kbin even worse. A lack of downvotes is, in part, what made facebook so vividly toxic and rife with hate speech and fake news. When a site lacks upper moderation and a method of inter-community moderation, there is no way to filter out bad content and bad users.
Removing downvotes is something wanted by people who dont want content filtered. Showing downvotes is something wanted by people who want to weaken filters. Weak or nonexistent filters is what allows the worst aspects of the internet to fester and rot.
I did literally say I am drawn towards instances that would refuse to federate with privacy free instances, which includes the ones that make votes public. In the exact same way I would not want federation with instances that make your ip or view history public.
