The One Video To See If You Didn't Watch Zuckerberg's Testimony

WASHINGTON, DC — Mark Zuckerberg's appearance on Capitol Hill to answer questions related to the Cambridge Analytica data breach revealed much about the tech CEO and Congress' apparent lack of understanding about digital privacy and how Facebook works.

Zuckerberg appeared on Captiol Hill over a period of two days. A photo of his notes taken by Associated Press photographer Andrew Harnik showed his talking points, which said things like no social security numbers or credit card information were compromised, that he wasn't planning on resigning and that advertising was one of the only ways to keep the social network free and accessible to the largest number of people.

Zuckerberg was also apparently coached to address members of Congress as "Congressman, Congresswoman, Senator," when giving his answers, Slate observes. A video compiled by Slate shows Zuckerberg addressing members of Congress by their titles over and over again. Slate's conclusion was that Zuck sounded like he was overdoing it while the intent was probably to show respect. The video ends with Zuckerberg's startled response to Sen. Orrin Hatch's question on how Facebook sustains its business model when users don't pay for the service.

"Senator, we run ads," Zuckerberg said.

Zuckerberg acknowledged that regulation of the social network is an inevitability but whether Congress will act to take up and pass legislation to do so remains to be seen.
