That most people claim that the invasion of privacy as the worst part of online advertising rings true to me too. I don't mind ads. I detest the idea that people are profiling me. Retargeted ads, where I've just been searching for a flight on one site and then I visit a completely different site that has an ad for flights to and from my chosen destination, drive me to deliberately avoid that company in the future if I can help it. I find it completely disturbing. Profiling is what makes me primarily use an ad blocker.
