of all the brands, apple cult brand is the strongest, it's hard to argue when it's already spelled out word per word in their leak internal memos that their intention to stop tracking was because they wanted a cut of FB's ad revenue.
Their execution under the guise of caring for user privacy is a master class though, it's impeccably done, there should be a case study done about this.
It is just first-party advertising for App Store, News+ etc.
The sort of channels small businesses were never going to use anyway.
