This is bothersome seen from my perspective of both a CC advocate and European national chapter and as a CC using maker. In my experience makers using CC use CC because they want to limit the ownership current international copyright laws and treaties bestow on them, as they see them as obstacle and greedy, and generally not serving the maker but later exploiters of artefacts. Also the perspective of contributing to the common good / pool of culture is frequent, and counter libertarian angles. I need to check but I think it might also be a ways off from Lessig's original idea for CC as expressed in [[Free Culture by Lawrence Lessig]].
