We have already spilled lot of our private info on the floor of the big giants like google and FB. I have heard that google has not deleted a single bit of search that we have done till date, just imagine how much of our information are in their hands. Facebook too failed in securing its users' data and that is a big threat to everyone's privacy. Google even spies through our microphones in our mobile phones and laptops. God save the world. Amen!
