That article has loads of assertions of personal opinions of the author and besides a glaring lack of evidence, didn't even bothering googling how the local public radio editorial policy isn't centralized. Consider that NPR does not have a radio broadcast at all. Affiliates do. Affiliates who can air any combination of content produced in house, by NPR or by other affiliates all catering to local markets. Local affiliates derive most of their funding from members but NPR is prohibited from soliciting which is why they also have corporate sponsors. The sponsors do not exert editorial control and don't even have access to affiliates who determine what goes to air.
