For instance, the source for the linux OS that runs on the Mattel "JuiceBox" (which is being used here and there as an experimental ARM linux system) is freely downloadable, but the video player that it loads to show cartoons and such is a proprietary application and not available. (I don't know exactly how this works for an "embedded" box without clear differentiation between OS and application. No doubt vendors want it to work one way, and RMS quite another.)
