>On the contrary page two of the FAQ states "The design of the PA prompt differs from that of the ATT prompt for third-party app publishers."
The PA prompt is a voluntary (required in the EU?) prompt Apple shows requesting opt-in for personalzied ads. It is of course different from ATT because it doesn't involve third-parties whatsoever.
If Apple wanted, it could mirror Facebook's behavior (in the rest of the world) by not showing any PA prompt. This would greatly increase the number of people who are exposed to personalized ads from Apple's first-party ad network.
>The FAQ strongly implies that they did track across apps and websites, i.e. "draws on user data from its own ecosystem [which involves multiple apps and websites]",
It draws on data from Apple's first-party apps.
>Nothing in the FAQ supports that this was voluntarily and not required by law. In fact it strongly implies the opposite "the General Data Protection Regulation (GDPR) and the provisions of the ePrivacy Directive, in particular, require app publishers to obtain user consent for certain types of data processing" ... "Insofar as Apple requests consent to its own processing of user data for advertising purposes,"
My comment refers to Apple and app developer behavior in the rest of the world.
>Noting in the FAQ supports any of these claims.
That is my informed opinion based on following this story since the very beginning.
