Associate editor and columnist Ruth Marcus has left the Post after it refused to publish a column “respectfully dissenting” from owner Jeff Bezos’ new limits on opinion coverage, reports The New York Times’ Ben Mullin and Semafor’s Max Tani. Marcus writes that the new policy “threatens to break the trust of readers that columnists are writing what they believe, not what the owner has deemed acceptable.” It’s also reportedly lost the Post at least 75,000 subscribers.
