"If you think Facebook knows a lot about you, try Google," Kevin Landis, CEO and chief investment officer of Firsthand Capital Management, told CNBC's "Closing Bell" on Monday. "They know every search you've ever made and everywhere your Android phone has ever been."
Despite people's fear of privacy disclosures after the Facebook data scandal, users and investors alike don't seem to mind Google harvesting their data. Google's parent company Alphabet on Monday reported first-quarter earnings that beat expectations on earnings per share, revenue and operating income.

So, if you think that Facebook is bad, Google is even worse, especially in regard to them keeping all your emails and the locations of all your android locations.
However, from what I have read Facebook makes a lot more money selling all your information whereas Google is more likely to "HAVE" this information and "What are they going to do with this information?" 10 years, 20 years or 30 years from now? It's hard to say. Does Google want to blackmail us or just sell us stuff? It all depends upon the motivations of who controls all this information about everyone.
Could other people steal this information?
Likely governments and criminals already have!
