There’s a fine line of acceptable ads that I think websites stepped over and now everyone hates ads of any kind. They were mostly unobtrusive with the odd banner ad, slowly the whole web started getting more and more aggressive with ads, targeted ads begun and then people wanted rid of them. The cycle of more blocked ads, so they put more ads on, but then more people block, then they add more ads… on and on. Now it’s too hard to convince people to go back to acceptable unobtrusive ads.
