Your original comment does not distinguish between multiple first and multiple third party apps. This is defending a comment you did not write. Regardless the FAQ you cite does not say whether or not Apple is collecting or aggregating with data from third party apps (just that it is not using the apple specific identifier for advertisers to do so) nor say that not doing so is why the PA prompt is different. And again it does not support your assertion that it is voluntary (in or out of the EU). So again your claim that page 1 of the faq supports all of your original comment is wrong - it supports literally none of it.

No, your comment explicitly refers to the behavior of Apple in its interactions with the german regulator, which is its behavior on germany, not the rest of the world.
