Thanks.

So it looks like Interoperable Private Attribution is mostly Meta people; there's one guy from Mozilla, Eric Rescorla. Eric is not notable for adtech achievements; he's notable for his contributions to internet privacy, and security and cryptography.

Apparently the proposal is to store the match key in browser local storage; which means that you can block it by setting local storage to zero, or by regularly cleaning-out local storage.

That article doesn't mention once the privileges that should be granted to the user. It does mention the powers of the user agent, but that really means the browser manufacturer.

I don't understand how this can work. What is to prevent combining the new ostensibly privacy-preserving attribution with existing tracking technology for enhanced identity tracking?
