Don't forget this is the information era, everything is about information. Every time you shop.... you don't think retailers aren't keeping track of what you buy, how many, at what frequency? your web browsing, stored on servers at google, yahoo, etc (why do you think google made google+ which combines all your google accounts?) everything is about gathering information, storing it, and being able to access it and keep it safe.
