I mean, like it or not, piracy is incredibly dark grey (if not outright black) in the eyes of the law. Its one of the reasons there is such a strong focus on "abandonware" and "oh, this is about digital preservation" in the various circles. It doesn't fool anyone but it is at least a stronger protection than the old "Hey FBI. You aren't allowed to look at my DC++ share" folder that people had back in the day.
