2 things about this. 1. The user was led to their misconception because the ui did not provide any better conception. Perhaps the label should add the words "... by a repo admin" or something. 2. This still does not explain why there should be any difference between an anonymous and a logged-in user for merely reading. If the repo owner is to be given the power to hide comments, why should a logged-in but otherwise unspecial user be able to override that? If a logged-in but otherwise unspecial user should have the option to unhide, why only when they are logged in?
