I think some of it could be the unthinking inclusion of 3rd party libraries that seems to go all through the mobile dev community. Just thinking of crashlytics, which is incredibly popular, and on it's own, isn't terribly invasive. But of course, google now owns it, so every time you go to your console, google is constantly pushing some further invasion of privacy to improve your insights. There's load of things, even apart from deliberately malicious libraries, that will use analytics to fund their free tools. What do you know about your easy to implement cloud synching db that saves so much time?
