That's funny! You can not opt-out of Google tracking, they just make it look like you can. There is a reason Google runs the Google Play Store, fonts.google.com, maps.google.com and gmail.com for instance. It's not because they are nice, it's because they make oodles more money hosting that stuff free and yanking data from you for their actual money making business.
Except for the Play Store, all of those apply equally to iOS devices. You do not even need to log into a Google account to use an Android device, even one purchased from Google. iOS is strictly worse in the amount of privacy allowed to its users.
