Agreed. More to the point, it can be argued that if I do not want to consume ads, my browser displaying them means my browser is broken.

This entire thing where your attention is hijacked because you have a passing interest in subject X is out of date. Yes, we've had passive ad sponsorship of all kinds of events in times past, but it wasn't a situation where the advertisers monitored your every move and were aggressively interfering with your content consumption. It was a situation where they wanted to be recognized for supporting the content you were consuming. Ads have gone from being passive, supportive, widespread constructs to being aggressive, directive, in-your-business constructs. Not good.
