"Such perspective requires that the critical power of Free Software be brought under scrutiny, moving from the undermining of the discourses of Intellectual Property, organization of work or hierarchy, to the understanding of the epistemological implications for computer science and software engineering. From this point of view, arguments that see the epistemology of computing as the locus of production and reproduction of long-standing inequalities in power relationships, are suggesting new areas of enquiry. Is Free Software a form of critique of the epistemological basis of computing? Is it possible to connect its critique of Intellectual Property and organizational forms to the critique of software development premises as a professional and research practice? Those are the questions this special issue is trying to answer. To promote an interdisciplinary debate, we encourage submissions of theoretical and empirical papers authored both by social scientists, in a broad sense, and by computer scientists (joint papers are most welcome). We expect the authors to envision the potential for Free Software of being a form of cultural, practical, and material critique." - Miguel Caetano from Bookmarklet
