Apple doesn't have to even roll out a user-targeted ad system. All they have to do is offer a buying platform where you can track conversion on Apple devices and software better. In other words, they don't have to offer more user-level accuracy to the end buyer, they simply need to measure campaigns more accurately on iOS (a bit of a simplification but not much). That alone will make their DSP a dominant player in the industry.
