But Apple software is proprietary, not friendly to open soure developers and you never know what that software is doing. Maybe they are streaming your data directly to "cloud" operated by NSA. Or iPhone doesn't upload anything to cloud?
Without the app store and the google ecosystem, android experience is poor at best.
Try this: On Google's Appstore, find a flashlight app that doesn't upload your contacts. Now on F-droid, try to find one that does. This is not an easy challenge!
Even if you have a completely “open” operating system on your phone, your communications is still going through a carrier that could be “operated by the NSA”.
I take your point but android is similar in some respects (Google probably has less interest in your privacy than Apple does).
