"You have full control over how much information you give Google when you use the device." You don't even have control over how much information you give Google when you use their search engine on a desktop computer. Even if you sign out of Google, turn off cookies and use a browser without geolocation. Google will always continue gathering information about you and providing you with custom search results. But even if you could turn off all data collection, the vast majority of users won't know about it. As a result, they pay Google by sharing their personal information, their interests, their location, their contacts, etc. Google's core business is advertising, they can't help themselves.
