Facebook does not exist as a public service. It is a data collection and advertising revenue generation company that functions solely to collect and aggregate data for sale to the highest bidder. They track you around the internet (as many websites do) in order to gain as many data points about your life and behavior as possible so as to extract as many dollars from as many consumers as they possibly can. Once you realize that Facebook (and other social media, and in fact most information disseminating sources such as tv and radio) exist not to give you relevant information or help you keep in touch with others, but in order to use you for maximum profit, when you realize what a scam it all is, it’s easier to walk away. I don’t see any difference between people like Martin Skrelli and Mark Zuckerberg. I think they are both crooks.
