Can someone clarify that?
In the example you give, the OGL means that OpenStreetMap has to attribute the government, but the OGL does not require that OpenStreetMap should force that same requirement onto anyone who uses OpenStreetMap data. The requirement to attribute the government is not "inherited". Similarly, the ODbL requires that if I produce a pretty picture made from OpenStreetMap data, I have to attribute OpenStreetMap, but I do not have to force any users of my picture to also attribute OpenStreetMap.
