Where do you think those vast resources come from? Those resouces come from selling every ounce of information on you they can, they are even reading your email before you even open it. http://www.usatoday.com/story/opinion/2014/09/04/google-spyi...
It frustrates me no end to read stupid comments like yours. Of course they use what you freely give them to their advantage. There are plenty of email hosting options, viable search alternatives, viable mapping alternatives etc etc. Google don't have a monopoly on anything. They make you a simple trade; compelling products in return for profiling you, what you say, where you go and what your search intents might be.
I know perfectly well where google's profits come from. Who reading this site doesn't?
