Zuckerberg on whether European regulations should be applied in the U.S.: "I believe everyone in the world deserves privacy protections ... I think it's certainly worth discussing"

.@LindseyGrahamSC actually doing a good job of laying anti-trust groundwork on Zuckerberg with questions about meaningful competition for Facebook. For all of Zuckerberg's claims of competitors, FB does have a monopoly no one comes close to matching its social graph.

the CEO of Facebook admitting that the average user does not read the entire TOS.

It's obvious to literally everyone in the world this is the case. But lawyers will point to the TOS at the end of the day, every day, in a company's defense.

Zuck tried really hard not to say whether he could support Sen. Markey's Consent Act, a bill that would require companies to obtain explicit consent from consumers before using their data for advertising. Zuckerberg really wanted to stick to "that's a good principle!"

Zuckerberg vowing again that AI is the solution to addressing problematic and harmful content on Facebook.

Brian Fung (@b_fung) April 10, 2018

Zuckerberg has now repeatedly said that Facebook will increasingly move toward AI automatically taking down and even *blocking* posts. Because that's what our policymakers want: in one breath they complain of Facebook's unchecked power and in another demand they use it even more.

Zuckerberg (who earlier was fear-mongering about Chinese tech companies) is hesitant to answer Senator Sullivan's "softball" question about whether it would've been possible to start FB in China (remember, Zuck really really really wants to get into China)

Sen. Thune asks Zuckerberg if he will err on the side of protecting speech, including from all corners. "I want the widest possible expression," Zuck says, saying political ideology isn't a determinative factor.
