The actual UX of this is very telling. Apple haven't actually clobbered this, they've added a modal "This app would like to track you across apps, Y/N". Apple haven't actually said no to this, they've given the user the ability to say no. I find this an interesting distinction, because the only logical way to extrapolate "the user now has a choice" to "apple have ruined this for us", is to admit that given a clear and effective choice, the user will opt out of this almost every time. Which is why this one is a "good!". If every user wants to opt out of this, perhaps it should never have been viable in the first place.
