The problem is that the ad vendors couldn't keep it in their pants. The ads you're talking about are a common vector for delivering malware onto people's PCs, and absolutely destroy the usability of sites. Between tracking cookies, popups, full screen banners, autoplaying video, flashing ads, and their unbelievably high weight in bandwidth - the internet is fairly unusable if you don't block any ads

Bear in mind that many basic privacy features destroy ads by breaking tracking and fingerprinting. Its impossible to get a browser in that doesn't filter out behaviours that have been used to deliver ads

Creatives can and have adapted their strategies away from what is a very specific form of ads: the disruptive full screen ads, or banner ads. That's only one form of advertising that everyone utterly detests. Sponsored content is much more popular with the end users, and much more effective as well because its way less disruptive. Some people hate that, but overall the tradeoff is significantly better

We shouldn't confuse a single type of widely blocked advert with all advertising being blocked. Banner ads have very poor efficacy at delivering sales anyway
