Google didn’t eliminate malicious ads - adblockers and easylists did that.

I hate to break it to you bud, but the full-page ads never went away - they just look like content now. You know why you need to scroll for 9 pages to see the ingredients to a recipe?

Google created the pageview driven business model that incentivized the internet to be filled with hostile UX, low-quality lists of paged content, affiliate spam, etc.
