Good. This is the sort of thing legislative bodies should be focusing on, not whether you can use first-party user behavior to improve your own damned product without explicit informed consent (looking at you, CNIL).
Apple's crackdown on third-party advertising only to supplant them with its own solutions is exactly the kind of monopoly abuse of power
Apple wrapped up its own advertising business pitch in user privacy. If they really cared about user privacy, they wouldn't have introduced Search Ads, SKAdNetwork, or given any option for users to opt-in.
They don't care about your privacy. They just don't want the competition to do better, for less, than they charge in their ads, because if there's anything we learned from iAd, it's that Apple is actually garbage at advertising services.
If you don't think Apple is interested in continuously building out their own ad offering on your data, they wouldn't have quietly hired Antonio García Martínez, and then had to let him go when female employees brought up how much of a creep he was - but they knew that going on since... ya know, he's written a book about it beforehand (Chaos Monkeys).
