The debate over Facebook's political ads ignores 90% of its global users | Julia Carrie Wong

What do Zuckerberg's bromides about American values mean to Facebook users in Kashmir or the Philippines?

When Facebook wrote to Joe Biden's campaign to say it would not back down from its decision to exempt politicians from its ban on advertising false statements, it was not Mark Zuckerberg or Sheryl Sandberg who signed the letter, but a not particularly well-known staffer named Katie Harbath.

As Facebook's director of public policy for global elections, Harbath has been a prominent voice in defending the controversial policy. "If people have a problem with Facebook's policy, they have a problem with the way political speech is protected in this country," she wrote in an op-ed in USA Today this week. "Fundamentally we believe that, in a democracy, it's better to let voters make their own decisions, not companies like Facebook."
