We manage so many of our daily activities online that the web has inevitably turned into a giant pool of personal data, which is exposed to a variety of risks, as was the recent case with Facebook.
It is a complete operating system designed to be used from a USB stick or a DVD independently of the computer’s original operating system. It is Free Software and based on Debian GNU/Linux.
The simplest explanation for this is that Facebook uses that data to make money. No, Facebook doesn’t sell your data. But it does sell access to you, or more specifically, access to your News Feed, and uses that data to show you specific ads it thinks you’re likely to enjoy or click on.
