Mark Zuckerberg gave testimony during congressional hearings regarding user data and privacy rights because there is a significant concern about Facebook’s role in the shaping of our democracy.
Facebook’s ongoing Cambridge Analytica data-privacy scandal, and how Facebook has failed to guard against other abuses is the reason Zuckerburg was asked to appear.
To make a point about the importance of privacy, one senator asked whether Zuckerburg, “would be comfortable sharing aloud the name of the hotel where he stayed on Monday night, or whether he would be comfortable sharing the names of the people he has messaged this week.” Uncomfortable, Zuckerberg replied, “No. I would probably not choose to do that publicly here.”
