I appreciate the good things Google does for me; they are many. But I don't think protecting my privacy, much less securing my data even from themselves, is their priority.
Funnily, I don't think there is any other company that protects users private data better than Google. Not military, not Apple, none of them come closer to it.
Google are good at preventing people hacking their servers, but they also broadcast your private data to thousands of third parties every time you open a webpage. Facebook and Google's approach to data security is lock it down so only they and their partners can access it. It does nothing for your privacy.
