Ah.

In that case, it's going to fail the test of being just as good pretty hard. Being able to target flexibly and based on user actions (or location, or other salient data) is really valuable to advertisers, in a measured-in-units-of-currency sense, and thus to publishers. It means better results from more narrowly targeted ads, and it also means more valuable ads to publishers.

It's perhaps not impossible, but it strikes me as a difficult thing to convince advertisers and publishers alike to take on.

Yeah I don't see the online ad business ever adopting something else because it's "as good", I think that browsers should drive this and ensure sites simply don't get this type of information, so the adoption to something better (for consumers) is driven by necessity.

The adoption of a system like the one I'm describing rests solely on the fact that the current information ads are based on, would dry up for one reason or another. Either because they don't dare use it (regulatory) or because they simply never get the information (technical).

I was under the impression that the past years of rapidly evolving DNT, third party cookie blocking, widespread use of adblockers (even in phones) etc was already rapidly drying up the amount of information available to track users? Perhaps I'm overly optimistic?

The ad industry has proven very good at finding new ways to track people, defeating each new approach to block tracking. They've proven similarly good at learning to infer things they haven't actually been directly told, which is very helpful for getting around regulatory barriers.

In practice, not everyone keeps up on their patches, meaning they tend to be vulnerable to known tracking methods. Total ad blocking prevalence is not as high as one might guess: https://digiday.com/media/ad-blocking-charts/

Additionally, neither Apple nor Google is incentivized to make it easy to block ads on their devices. The only people I know who have done so are ones who have gone to non-trivial lengths to accomplish this.

Sadly, I think you may be excessively optimistic.

Pretty much AdBlock could do that.

It let's you opt out of serverside-profiled and unprofiled ads, and opt-in into relevant ones profiled on client side.
