It would be much harder to block ads if they were more like newspapers and just a part of the page you were viewing, instead of imported from a different source.
But in order to do that the site themselves would be responsible for the ads they display instead of blaming their ad service, and they would lose out on all their tracking data.
So fuck em.
I have a similar story. People were fine with ads until they got too obnoxious and intrusive, and now the people making the obnoxious intrusive ads are crying that people are blocking them.
