In my experience people ~25 years of age and younger, who are not tech-savvy enough to install an adblocker, simply do not surf the web. Everything is an app, thus the internet browser becomes an online shopping (no/very few ads) and "googling" tool, though this second use is fading away as well with the rise of LLM chatbots. The ads baked into short-format content are much less obtrusive than the popups or fake download buttons of yore—though in my view this makes them even more insidious. I've witnessed my friends not even realize a video was an advertisement until they'd already watched it in full.
