Ok, let's break down your claims one by one and compare to the text of the FAQ...
> Apple didn't give itself better dialogs.
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."
> It never did third-party tracking across across apps or websites
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 also voluntarily showed a dialog explicitly asking you to opt into personalized advertising.
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,"
> Facebook doesn't show anything similar when you use Instagram or the Facebook app, because that would be undoubtedly bad for business.
Nothing in the FAQ supports this claim, and as discussed in other comments here it is simply false.
> The German regulator settled because the facts are simply on Apple's side. Apple settled because at the end of the day it's no skin off their back if the EU now wants to weaken privacy protections to benefit ad-tech.
Noting in the FAQ supports any of these claims.
