It seems like you didn't bother to read the entire article because the author does go into the ethical and privacy related concerns about ads. It is always interesting to read about people's opinions on topics such as this, and the fact that you dismissed it outright with such ignorance as to call it a bad-faith argument tells me you are not open to hearing opinions that differ from your own. As a result, a downvote of your comment feels appropriate (if I had the points to do so). But hey, at least you're probably a decent person (really!).
