I think the main complain anyone would have with this is, only we admin can look at the vote, and no one else can. This isn't a problem in Kbin or any other platform that allow one to do so.
I only check the vote to see if there's any brigading, other than that, i have no issue with other admins snooping or whatever. Ohh to be clear, all of us admin can see the vote everywhere, getting a new instance yourself will not solve anything.
I think there is an assumption that is rooted in how reddit worked, that votes are anonymous. People operating under that assumption might not like having that blanket ripped off. It would be different if it was up front from the start.
