How would this make it at all harder to build a profile or change anything? Correct me if im wrong: Google, or whatever ad tech, gets data from an app which sends an email or oauth data to the IDFA. The email or oauth data stays the same even if the ad uuid changes month to month. Over many many apps. I personally would actually rather have Apple control this and start competing with FB as a mobile ad network. I think they could present a solution which fits with their privacy appeal while also cleaning up fraud and dictating better ads formats / rules I would like to think that space isn't totally won yet.
