Facebook's Zuckerberg testimony before Senate committees goes smoothly

Facebook (FB) CEO and co-founder Mark Zuckerberg testified on Tuesday before the Senate Judiciary and Commerce Committees — a charged, five-hour hearing that saw senators at times lob criticism at Zuckerberg while grilling him on the recent Cambridge Analytica scandal, the company’s role in the 2016 U.S. presidential election, and its position on government regulation regarding user privacy.

But it would appear that Zuckerberg prevailed on the first day of Congressional hearings, at least among investors who reacted favorably to what Zuckerberg said. Facebook stock was up 4.5% to $165.04 per share when the markets closed prior to the end of the hearing.

“If you and other social media companies don’t get your act together, none of us are going to have privacy anymore, ” Sen. Bill Nelson, the senior senator from Florida, remarked to Zuckerberg before the Facebook chief executive’s opening remarks.

At the start, an apologetic Zuckerberg stuck closely to his prepared remarks, which were released Monday.

“Just recently, we’ve seen the #metoo movement and the March for Our Lives, organized, at least in part, on Facebook. After Hurricane Harvey, people raised more than $20 million for relief,” Zuckerberg said in his prepared opening remarks. “And more than 70 million small businesses now use Facebook to grow and create jobs. But it’s clear now that we didn’t do enough to prevent these tools from being used for harm as well. That goes for fake news, foreign interference in elections, and hate speech, as well as developers and data privacy. We didn’t take a broad enough view of our responsibility, and that was a big mistake. It was my mistake, and I’m sorry. I started Facebook, I run it, and I’m responsible for what happens here.”

During the Senate Judiciary and Commerce Committees’ Q&A, Zuckerberg emphasized his goal of informing users about the different ways in which in their data could be used. He also discussed the challenges of balancing being explicit with privacy policies with making those same policies simple and accessible enough for users to understand.

Zuckerberg also discussed how much Facebook has evolved since he started the social network from his Harvard University dorm room in 2004. Back then, when Facebook was an exclusive, college-only social network, policing content was a matter of having Facebook users flag content to be taken down. Flash-forward 14 years, however, and Zuckerberg acknowledged such methods simply aren’t enough. In particular, Zuckerberg clarified that Facebook should have banned Cambridge Analytica earlier than they did, given its role as an advertiser in 2015, adding that Facebook made a mistake in not doing so.
