If you use Google Maps, you're giving away tons of data about who you are — that is, where you live, where you work, and where you spend your time. For all that information, though, it has still done its vital job: directing people to the places they needed to go. However, the company has slowly grown its profit motives for the app through the development of potential ad products and major pricing changes for its APIs. These decisions could add to Google's already-titanic influence over its users' everyday lives.
