«The great hack» is about how companies like Cambridge Analytica take peoples data and use it to promote different products. These companies can also use the information for political campaigns. For example, if you support Joe Biden you are more likely to get positive media coverage about Biden and negative about Donald Trump.
The «social dilemma» is similar to the great hack. Both films talk about the issues evolving social media and how it uses information about you. «Social dilemma» shows us how this negatively affects us. There is a teenager in this film that gets swept into social media and starts to believe in different theories. The boy ends up arrested because he ends up at the wrong place at the wrong time. This film thought us a lot about how social media works behind the scene and how it can affect us negatively.
