Apple's already shown they don't like this behaviour with their randomised MAC addresses in iOS 8+.
And elsewhere in the thread people called out the fact apple had already introduced support for ad blocking. So Apple’s privacy-positive posture was already in the air.I think there is a sense in which privacy was already a differentiator for Apple in iOS (as contrasted with Google’s motives in android in particular of course) - so this did feel like a not completely implausible way they could go to double down on that differentiator.
