Doing privacy-respecting ads is not hard, generate the relevant cohorts on the client, pull either all ads, or k-anonymity if the pool of ads and expected size of cohort are large, and then use that pool of ads.
But that means they don't get "useful" ad metrics in any form, so its a non-starter for the IAB.
