> More valuable to who?

To the paying customers - advertisers.

So? Google doesn't care about its users, and hasn't for a very long time now.

Google became profitable purely because they delivered the most value to advertisers, by way of having the most eyeballs. More relevant advertisements are not going to reduce the number of eyeballs that google sells.

> If, as a user, I see ads that are more directly targeted at me, that is a negative value in a search engine.

And those users will be lost in the noise, a statistical rounding error, if that. Losing unprofitable users helps Google become even more profitable.
