The news: Mark Zuckerberg said Facebook should “err on the side of greater expression” during a 35-minute speech at Georgetown University yesterday in which he tried to cast the platform as a champion of free speech and democracy.

Facebook’s CEO defended his firm’s recent decision not to include political ads in its fact-checking program, saying “people should decide what’s credible, not tech companies.” Zuckerberg said he had been tempted to pull Facebook out of the political ads business entirely, as it’s highly controversial yet makes up a tiny part of the company’s overall revenue. But he decided against it, arguing that such a decision would favor incumbents and hurt smaller, up-and-coming candidates. You can read a transcript of his whole speech here.
