Disclaimer: I used to work on Google Search Ads quality models

> Google obviously tracks everything you do for ads, recommendations, AI, you name it. They don’t even hide it, it’s a core part of their business model.

This wasn't the experience I saw. Google is intentional about which data from which products go into their ads models (which are separate from their other user modeling), and you can see things like which data of yours is used in ads personalization on https://myadcenter.google.com/personalizationoff or in the "Why this ad" option on ads.

> and it’s very much not necessary or even a sound business idea for them to do something else

I agree that Apple plays into privacy with their advertising and product positioning. I think assuming all future products will be privacy-respecting because of this is over-trusting. There is _a lot_ of money in advertising / personal data
