> The long-term solution to ATT, though, is to build probabilistic models that not only figure out who should be targeted (which, to be fair, Meta was already using machine learning for), but also understanding which ads converted and which didn’t.

If Apple sees Meta as a threat now that Meta are getting into devices, all they have to do is add a rule that probalistic models of conversions beyond a certain scale of computation aren't allowed, and that anyone operating over $X amount of revenue on their platform is subject to invasive audit to make sure they aren't doing it. They can figure out a way to say it is for privacy but that they themselves can do it, or they can make it so users can opt in to probalistic models with different defaults and wording on the dialog for third parties vs for Apple like they do now for tracking (Apple calls others' tracking in the prompt 'tracking your activity', for their own they call it 'ad personalization').
