I remember a little while ago a thread with someone from kbin gloating that they could see what everyone was voting, and accusing the people upvoting comments they disagreed with of being bigots in a vaguely threatening way obviously intended to produce a chilling effect, and people found this surprising because that information is not public on most instances.
I basically agree with the people saying open info is just the nature of posting on a public forum and of federation, but there could be improvements, even just in awareness of what is and isn’t private.
