The adverstisers have it backwards
If anything's "damaging the online experience", it's the damn ads themselves, not the ability to block them. The advertisers only have themselves to blame. They brought this on themselves. Most people were OK with a reasonable amount of ads, but they had to push things. Very few people complained about a simple banner, but when it mutated into those obnoxious flashing / shaking boxes, as well as the annoying pop-ups and boxes that take over the entire page and lock it up, then people started getting fed up and blocking the ads. And let's not forget about those damned fake virus scanners. It's getting to the point where it's dangerous not to block the ads.
