You're diving too deep into "protecting my privacy etc etc etc". If you are so concerned about your privacy, get a flip phone, forget about iOS/Android/etc, then only your cell operator will know what you're doing.
Both Apple and Google proved they will do whatever they want with their platforms and services. Still, Android will give you much more flexibility to decide how to do the things. Choose a phone / OS based on your likings and features, and stop worrying about non-sense.
