Funny, I remember the Internet from over a decade (or two) ago and it was a mess of full-screen ads, seizure-inducing animations, infinite popups, etc. that Google helped eliminate.
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.
We could break their back if we required them to respect trademarks.
Google captured the browser with 92+% "browser -> search" funnel market share.
They turned the URL bar into "search", meaning that the method of finding trademarked companies and products now flows through a competitive bidding marketplace where competitors can slide in front of your hard-earned brand.
