I have my suspicions about NPR having seen them report on things that I was personally privy to and get it wrong. I suspect in their case it is a case of not doing a full job of fact checking.

For instance they reported on the capabilities of the Spruance Class destroyer. I served as a Plankowner on one between 1979 and 1982 so I know a thing about the class and in particular the USS Cushing DD985. They reported capabilities that the ship flat out did not have. (Interestingly some features they reported on did come along later in SpruCan lifetime)

Right on about BBC. I find they put out more fact and less spin than other news organs.
