I am doing a hobby project on compiling a topographical wall map, with no commercial intentions, in which OSM data would be very useful. However, one of my crucial data sources doesn't allow commercial use. Therefore, I cannot use OSM data, which allows commercial use (as stated in the "Legal FAQ"). I think this is a big paradox: OPEN street map, defined as OPEN DATA, cannot be used in strictly non-commercial products... Or have I got it wrong?
