I'm not disagreeing with you, but that still doesn't refute the argument that you're selling your audience to someone else without their consent (and before you say "then don't use the site", you don't get to choose whether or not you're exposed to the given sites ads until you go on it, in which case it's already too late. Unless, of course, you use an ad-blocker -- which is why I'm of the opinion that people should use ad-blockers, but I disagree with the article in that I feel there can be cases of responsible, acceptable advertising. Things aren't so black and white, from either side)
