Not true at all..this would have significant monetary impact. If advertisers lose to ability to monitor purchases at a granular level attributed to advertiser specific initiatives they will not spend and that has a chain effect that trickles to apple since they take 30% cuts of all in app revenue. If advertisers pull the plug on in app purchases and go around...they may go the route of removing IDFA to screw over advertisers for trying to go around their App store.
