It's not about privacy -- it's about power

The Facebook-Cambridge Analytica scandal isn't about privacy -- it's about power, says journalist Carole Cadwalladr. In conversation with TED Global Curator Bruno Giussani, Cadwalladr discusses the latest on her reporting on the Facebook-Cambridge Analytica scandal -- and what we still don't know about the transatlantic links between Brexit and the 2016 US presidential election. "Who has the information, who has the data about you, that is where power now lies," Cadwalladr says.
