Surely Google gets more data from Android. But it does get much more data on iOS than Apple would have you believe. Case in point - Apple ostensibly prevents apps from uniquely identifying devices other than through ‘safe’ ad and vendor-specific ids. But just implement Google Firebase Anonymous Authentication in an app and try to get it to forget your id. you can delete the app and all other apps from same vendor, reset your ad id, set ‘limit tracking’ delete all google apps, clear google logins & passwords on your device, update the iOS, and when you reinstall it still knows who you are. Short of wiping the phone completely (which I haven’t tried bc of the hassle) Google appears to not only uniquely identify your device in a pretty sticky way, but to sell & give away this capability to anybody who wants it.
