NPR lost the influence that it once had on Twitter, controlling narrative that suited their political ideology. So, it quit. That's great new for Twitter.

NPR is far worse than a state-affiliated media. Its coverage during the riots and protests following the accidental murder of George Floyd focused on "racially disproportionate policing". It wasn't journalism. It was BLM protest using NPR as a microphone. There wasn't a single show that discussed crime statistics. Policing methods were discussed to the extent that it suited the narrative that cops in America are a racist militant group.
