I'm not sure I understand your critique. It appears NPR has come up with an interesting approach to allowing discovery of content it has access to in the form of this app, but they understandably aren't planning to get into the business of providing access to all audio content in the world via their app. But you are not restricted to using the NPR app to listen to NPR. Their content is also available in numerous other ways, including podcasts and streaming radio, as well as traditional local radio affiliates. So what exactly is your complaint?
