Re: [proposals] Interoperable Private Attribution (IPA) (#2)

@medicinalcocaine3434 the document was using suggested edits and comments, it was with suggested edits that the document was defaced.

@santirely if you take a look at the technical proposal, you'll find details on your question. Briefly:
> Where would the match keys be stored in the device / browser / OS?

We are proposing a new _read-only_ API, which the browser/OS would expose.

> Could we adapt this solution so that it isn't so dependent on companies with a "large footprint"?

Any website/app is able to write a match key, so it's not dependent on any set of companies. However, the more cross-device coverage a given companies match key has, the more accurate attribution that uses that match key will be.

> What happens if suddenly Facebook or Google decide they'll only share their match keys with companies that play well with them?

We are proposing that any site/app be able to reference any match key. Match keys are not shared, and the ability to reference them is not controlled by the companies that set them.
