Marietje Schaake, International Policy Director at Stanford's Cyber Policy Center, Eurasia Group senior advisor and former MEP, discusses trends in big tech, privacy protection and cyberspace:

Will the testimony of the whistleblower be a game changer?

Now it certainly was a down week for Facebook, which also faced a major outage and new accusations by Frances Haugen, the whistleblower who provided a trove of information first to the Wall Street Journal, and then gave testimony before US Congress. She reminded the world of how little transparency we really have into what Facebook does and how its business models create societal harms. But really after a week of outcry, we need more than that. Only clear policies will bring back the balance between the power of private companies like Facebook and independent oversight.
