"Warren turns up heat over Facebook's ad rules," 15 Oct 2019

Sen. Elizabeth Warren (D-Mass.), a top-tier Democratic presidential candidate, is turning up the heat in her battle with one of the most powerful tech companies in the world, Facebook, as she shines a spotlight on the company’s rules on political ads... Critics have argued that Facebook is abdicating responsibility over its powerful platform, which reaches more than 2 billion people globally, while the company and free speech advocates have insisted it’s risky for Facebook to take more control over what political candidates are allowed to say. “The policies they’ve announced are an explicit invitation to politicians to spread falsehoods,” Paul Barrett, the deputy director of the New York University’s Stern Center for Business and Human Rights, told The Hill. “And that is not something that we ought to applaud.” 

... Facebook has emphasized that it believes politicians should be exempt from many of its rules on speech. Facebook runs a third-party fact-checking program, which adds disclaimers to posts that can be proven false, but it now says that politicians’ posts and advertisements will not go through that system.
