Facebook has agreed to pay a £500,000 fine, the highest possible, to the Information Commissioner’s Office over the Cambridge Analytica scandal, ending more than a year of litigation between the regulator and social network.

For almost five decades, the United States has guided the growth of the Internet. From its origins as a small Pentagon program to its status as a global platform that connects more than half of the world’s population and tens of billions of devices, the Internet has long been an American project. Yet today, the United States has ceded leadership in cyberspace to China. Chinese President Xi Jinping has outlined his plans to turn China into a “cyber-superpower.” Already, more people in China have access to the Internet than in any other country, but Xi has grander plans. Through domestic regulations, technological innovation, and foreign policy, China aims to build an “impregnable” cyberdefense system, give itself a greater voice in Internet governance, foster more world-class companies, and lead the globe in advanced technologies.
