"...Apple's own advertising services are integrated directly into iOS and were not subject to the same user journey, raising concerns that Apple had leveraged its platform control to favor its own interests."
This is a key point most, if not all, Apple-stans miss. It was good that Apple kneecapped providers like FBook, etc. However, Apple has the built-in means to track you without any opt-outs. Apple tracks you insanely, and justifies its "...privacy..." claim because it does not sell your info to third parties. Instead Apple uses your massive load of tracking/fingerprinting data to -- very succesfully -- enhance Apple's own ad system.
This was shown quite quickly after ATT was deployed.
Go ahead a flame away re: How Apple is the only company you can trust.
I do not trust a single thing Tim, Craig, et. al. say. They only want to increase shareholder value, and you and I are simply the tools to do this, and I have been an Apple advocate for decades.
