Google does not have an interest in showing you shitty ads. They have an interest in providing their clients with ads that are acted upon and that web users appreciate, and they have an interest in having a browser that does that with as little friction as possible.
I'd say their incentives are perfectly aligned with ours.
Speak for yourself. I hate advertising and would rather see that whole revenue method burn to the ground and pay the $2/mo or whatever to use my favorite services.
Ads have ruined everything they have touched (radio, satellite radio, TV, cable TV, satellite TV, magazines, highway scenery, etc) and they are well into the process of ruining the internet.
In addition to bloating every site and exposing you to higher malware risk, they encourage companies to violate your privacy as much as possible and exploit psychological weaknesses to get you to buy stuff you didn't want or need to begin with.
Google's incentives are to spread this poison so they are not aligned with mine at all.
Disclaimer: they work for Google
They also own the most popular way those ads are shown: through their web browser. This browser has the ability (at Google's sole discretion) to block shitty ads, of which all of them are run by their direct competitors.
So what's happening is, Google is giving themselves the right to block parts of the Internet they don't like, with the implied statement of "if you want your ads to be seen by Chrome users, buy them from us or else we might block them".
That is a classic protection racket. "Want your ads to be seen? Better buy them from us, or... bad things will happen."
Seems pretty reasonable.
