Looks to me as though they're trying to get rid of the sub. In the past, they have made a decision on removing mods of subs and putting new ones in without too much user interaction, and they have never directly asked if a sub should be left to rot before.
The fact that the conversation can not be had without it being anon says a lot about the decline of Voat's community.
Yeah making an anon anouncment seems quite bad.
Also the warent canary thing going on there as well either they got a full NS letter which would make them pretend the Canary isn't dead or the admins don't care enough to update their canary in a month which they can in a couple of clicks.
