As much as I want this to be true, I think this sentiment is really only popular on tech-savvy forums like HN. Most people don't use ad blockers, and I've had people get mad at me when I suggest that they do (directly in response to something where they are complaining about ads).
People that aren't tech-savvy don't want to think about tech any more than they already do. Having to understand something new about tech is just another problem to them. I'm not saying that as an insult - just an observation.
