The Nobel Committee has awarded its 2021 Peace Prize to Maria Ressa for being a fearless defender of independent journalism and freedom of expression in the Philippines, and particularly for her work exposing the human rights abuses of authoritarian President Rodrigo Duterte. But the prize is also a de facto acknowledgement that Ressa has become something of a one-woman personification of the struggles, perils, and promise of journalism in the age of social media. A longtime investigative reporter and bureau chief for CNN, she began thinking about how social networks could be used for both good and evil while covering terrorism and seeing how it was used to drive both radicalism and build movements for positive change. She originally founded Rappler, her Manila-based online news organization, as a Facebook page, but now she says that one-time Harvard student Mark Zuckerberg’s dominance as a worldwide distributor of news has become a boon to repressive regimes and a threat to democracy worldwide. Rappler’s mission statement is to speak truth to power and build communities of action for a better world—but for Ressa, speaking truth to power has come at a high personal cost. She has been subjected to harassment, criminal and civil legal action, and even arrest, even as she has refused to back off even an inch. When we spoke for this interview, Ressa was just finishing a visiting fellowship at the Kennedy School, where she was affiliated with both the Shorenstein Center on Media, Politics, and Public Policy and the Center for Public Leadership.
