Apple has an ad platform as well. Every Facebook ad user is using an Apple-made identifier to correlate interests instead of a Meta-made one. That apple made identifier so that they could control the ad space and sell their own ad platform:

Don't fool yourself into thinking that Apple is much different than Google. They are all selling your data. Google is just upfront that they are selling it.

I'm agnostic about Apple and Google, but the thing that strikes me is this. You ask Google, do you share my data. They say hell yeah. Do you profile me. Hell yeah we do. Apple has never admitted anything until they were caught out. Did you give China access to stay in their market. That's commercially sensitive. Do you use device information to profile us. Silence! They're just bad in different ways. Google is blatant. Apple is devious.
