Fact-checking Facebook CEO Mark Zuckerberg's congressional testimony

"Zuckerberg said user ownership of content is fundamental to the website. But the emphasis on informed and empowered users masks an important dynamic, said Woodrow Hartzog, professor of law and computer science at Northeastern University. There’s a gap between what the company allows you to do, and what it encourages you to do.

"Platforms like Facebook have overwhelming incentives to extract the maximum amount of value and data out of us," Hartzog said. "Facebook can engineer your consent to all kinds of data practices though obfuscated buttons, vague, abstract language, and a ceaseless stream of nudges, reminders, and efficiencies to get you to share.""
