This company's activity shows us why we should be worried about all the data we disseminate in our daily lives, sometimes knowingly, sometimes not.
The main take-away about this, in my opinion: these algorithms can find out information about you that you never gave away, just by analysing the massive data trail you leave behind you at all times by using connected devices and browsing the web. These programs know more about you than you know yourself. And people are willing to profit from that, instead of using the data for good, for a more functional, open, collaborative society.
And this is not a fatality. We could, for example, stop using services that don't respect our privacy, and push forward solutions that do. Alternatives do exist!
Privacy by design should be the rule!
