For example, this is the screen I'm showed when I navigate to www.producthunt.com: https://imgur.com/a/9GgLIBM -- like you can't even tell what website it is, they're covering their own logo with pop overs. This simply can not be good UX, or marketing. It's not a good first impression.
There are healthy websites out there but they're really struggling to punch through all the crap.
It's curious because I feel we've seen this process play out once before. In the late-stage dot com era, there was a moment where you had these websites that were just absolutely plastered in ads and vomited popups at you when you visited them in a way that is very reminiscent of today. It's in part what led to the first popup blockers, and later ad blockers. Search engines were also cracking down on this stuff pretty hard since they just weren't good search results.
I imagine Google is in an awkward spot because, since ads is their bread and butter, they can't meaningfully penalize these websites without eating into their own bottom line. Many of the most intrusive ads are google ads.
