I am beginning to believe that advertising (at all, on any medium) is an evil we need to do without. The "free stuff" that we get in return is never without consequences, as we're finding out. The "hey we built a thing you might want to buy" function can be done in different forms, better, I think. Probably by newspapers. I think we could start by taxing all advertising revenue by, say, 50%.
Taking away that "free stuff" is not without consequence either. Now people without means can't read the news, watch tv, connect with friends and family online, play casual games, etc. Are ads more evil than taking away free access for those without the means to pay?
I think "means to pay" is relative - Cambodian tuk-tuk drivers get cheaper, better internet access than Berliners. And they watch YouTube on it. If they didn't have access to YouTube for free there would be a huge market in producing Cambodian content for them to watch, priced appropriately for that market.
