Ads and tracking don’t have to be related. Physical ads in magazines and newspapers are still ads, but don’t report on who you are. Similarly, if you have a service connected to an account on your OS, it knows which tier you are on and can try to upsell you.
I’m not defending ads or Apple here, far from it as I hate what they’re doing. I’m just saying that while we’re used to privacy invading ads, not all ads have to be so.
