Adverstisers consistently prove their unworthyness
Flashing ads, then pop-ups, then pop-unders, interstitials, auto playing videos and user trackers. I have sympathy with good web sites trying to generate ad revenue, but the techniques that have been used over the years to stuff unwanted ads down our throats means that with very few exceptions, if I can't use an ad-blocker I'm not going to visit. If they would stop being such assholes, I suspect many would stop using ad blockers. I know I get tired of the drama of maintaining a good ad blocker. (the bastardization of Ghostery recently is a good example)
