Technology is a major part of our lives, and companies such as Facebook have immense responsibilities. Every day, we make decisions about what speech is harmful, what constitutes political advertising, and how to prevent sophisticated cyberattacks. These are important for keeping our community safe. But if we were starting from scratch, we wouldn’t ask companies to make these judgments alone.

I believe we need a more active role for governments and regulators. By updating the rules for the Internet, we can preserve what’s best about it — the freedom for people to express themselves and for entrepreneurs to build new things — while also protecting society from broader harms.
