you are tracked regardless of OS. Cell towers are tracking you, ISP is tracking you, speed cameras are tracking you, security cams also, your ID/passport is chipped, more and more of everyday need is online so they are also tracking you............
Android is tracking you so that google can sell adds. Annoying as hell it is seeing adds inside apps but there are far worse tracking going around and there's nothing you can do about it. They don't give a shite about anything else. Governments abuse that data far more than google.
And in a day and age when most people willingly put their life on internet and do most stupid thing for their 5 minutes of fame it's kinda pointless to talk about privacy. Sure, there are some systems which are worse in that regard than others, but ultimately it's much more about the users than about the systems.
