Yahoo, Facebook, Google, WhatsApp, Instagram and Microsoft all have one thing in common; for any service that they provide for free, they are harnessing your private data to be sold to advertisers.
Mirror UK recently published an Op-Ed titled Who Is Spying on You? What Yahoo Hack Taught Us About Facebook, Google, and WhatsApp in which the author says:
Think about this for a second. All those emails you’ve written and received with discussions about politics and people that were assumed to be private and meant as inside jokes for you and your friends were being filtered through CIA headquarters. Kind of makes you wonder what you’ve written in the past few years, doesn’t it?
The services be it free email or free instant messaging have been designed and developed in such a way that the companies that own them end up with a humongous amount of information about its users. This data is sugarcoated and called as Big Data. It is then sold to advertisers and marketers who in the garb of providing immersive and customized user experience follow every click of yours online. This is akin to rearing animals for slaughtering them later.
