The so-called Twitter Files, released ... by the independent journalist Matt Taibbi, set off a firestorm among pundits, media ethicists and lawmakers in both parties. It also offered a window into the fractured modern landscape of news, where a story's reception is often shaped by readers' assumptions about the motivations of both reporters and subjects. Mr. Musk teased the release of internal documents that he said would reveal the story behind Twitter's 2020 decision to restrict posts linking to a report in the New York Post about Joseph R. Biden Jr.'s son, Hunter. Mr. Musk, who has accused tech companies of censorship ... pointed readers to the account of Mr. Taibbi, an iconoclast journalist. Published in the form of a lengthy Twitter thread, Mr. Taibbi's report included images of email exchanges among Twitter officials deliberating how to handle dissemination of the Post story on their platform. Skeptics of Mr. Taibbi seized on what appeared to be an orchestrated disclosure. "Imagine volunteering to do online PR work for the world's richest man on a Friday night, in service of nakedly and cynically right-wing narratives, and then pretending you're speaking truth to power," the MSNBC host Mehdi Hasan wrote in a Twitter post. Mr. Taibbi clapped back on Saturday, writing: "Looking forward to going through all the tweets complaining about 'PR for the richest man on earth,' and seeing how many of them have run stories for anonymous sources at the FBI, CIA, the Pentagon, White House, etc."
