I'm not a utilitarian, but according to standard utilitarianism (as opposed to LW usage, which usually just means "consequentalism"), if it benefits people to a greater degree than it hurts them, then it is a good action.
Yes, I am asking because my suspicion is that many people who label themselves as utilitarian evaluate a situation like this one using deontology-like rules and not utility calculations and was curious if this is the case.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
