摘要：A philosophical approach to copyleft is a big deal. It brings together copyrights, TICs and, sometimes, the democratic model itself. Copyleft is the device that conducts all these social empowerments articulated on this new society of knowledge. However, it is needed to make a research on the origins of these new ideas and the implications that discourses and practices of the pioneering collectives have had from the beginning. We have pick out two of the main actors of the field of the production of Free Software: the Free Software Foundation and the Open Source Initiative. Through the analysis of the discourses we will elucidate if we can appreciate differences in significance of "free work" notion for both actors, the propositions that underlie its main ideas and the factual possibility of the copyleft as to its subversive perspective for the discourse of the traditional operators of cultural market.
