Like I just said, browser ad blockers have been around for well over a decade, but their installed base has been a pretty small proportion of users until the past few years. A lot of people don't seem to be hugely bothered by a certain level of advertising, at least not enough to go to the effort of installing an adblocker.

Personally, I'd much rather have no advertising at all, but until recently I tried to only block problematic sites, use ABP's Acceptable Ads, and so forth, because I want to support the sites I use regularly even at the cost of very minor irritation. I switched to a scorched-earth policy when it got so bad that many sites were suffering major performance degradation, and many others were plastered with bottom-feeding ads that were actively offensive to me. If things actually improve by some miracle, I'd consider throttling it back a bit.
