I've used adblockers, revanced, and whatever else for years, so I don't see many ads, but every time I'm on a computer without this stuff installed I am appalled by how many scams get through. At some point, Google must have realized that nobody is going to come after them for selling ad space to scammers (possibly because of section 230 of the CDA?) and hey, scammers are willing to pay enough for it to be worth it.
