Cool, I didn't know, but doesn't that imply it's a dark pattern? How many users know about this setting? Wouldn't it be better as Opt-In, and let the App Store prompt you when you set up your iPhone "do you want to opt in to interest based advertisin/etc"? When other companies do opt-out, they're usually heavily criticized.
