Elon Musk, the CEO of Twitter, has caused controversy by labeling National Public Radio (NPR) a 'state-affiliated media' outlet on the social media platform. The tag is intended for media organizations with editorial content controlled by a state, but NPR maintains it operates independently of government. After NPR provided proof that less than 1% of funding comes from government sources, Musk questioned whether Twitter had been consistent in labeling other non-US accounts. His comments are the latest in several moves that have caused upset among journalists and free press advocates. Musk has previously stripped The New York Times of its blue check verification, suspended accounts of journalists and responded with a poop emoji to communications from reporters. Twitter's decision to label NPR has been viewed as undermining public confidence in reliable news sources.
