The Washington Post was always bad. Movement liberals just fell in love with it because they hated Trump. Always a awful, militaristic, working-class hating neocon propaganda rag that gleefully mixed editorial and news, the only thing that got worse with the Bezos acquisition were the headlines (and, of course, the coverage of Amazon.) The Wall Street Journal was more truthful, and actually cared about not dipping their opinions in their reporting. I could swear there's a Chomsky quote about that.
People put their names on it because it got them better jobs as propagandists elsewhere and they could sell their stupid books. It's a lot easier to tell the truth than to lie well; that's where the money and talent is at.
