What FACEBOOK and GOOGLE are Hiding from world.

They're not exactly hiding that. We're all aware that those two companies, along with others, collect our information and generally use it to promote relevant products or what their algorithm's believe we want to see.

Amazon, Netflix, and others all do it blatantly. It's not a conspiracy, just something that originally had a good intent (and still does), but is not yet developed enough to provide a well-rounded stream of information.
