All of these companies are competing for your dollars directly and information that they can sell about you to other companies. instead of mining minerals, they're mining our data. You see it with things like so called anonymous data collection and researchers who have found that they can identify people just based on that same information. Any data collection about you, your e-mails, your e-mail habits, your web browsing habits, where you have lunch, what credit cards you use, what toll roads you traverse, what street speed cameras you pass it's all potential sources for data mining and taking a little more of your freedom and privacy. If you use a credit card, trust me they are selling your information, your preferences and tracking your habits so that if a strange charge shows up, they can detect fraud. At least that's what they say to you. Where you buy something also locates you as well, so if you shop locally, guess what, people can find out where you are. It's paranoia, it's the new reality so when you get that nice free Facebook account or the free GMAIL account it does come with some Terms of Service and they can change at any time to suit their needs, not yours. Google's business just isn't on search, it's on you. Facebook isn't about social networking, it's about social data collection so for all those people who think they have privacy and use these services, guess again.
So while you may not be plugged in as a battery to supply power to an alien civilization, you are a source of rich mineral data and you're being mined daily. If you're okay with that, just take the right colored pill and go back to sleep.
