he said the terms "free software" and "open source" stand for almost the same range of programs. however, they say deeply different things about those programs based on different things about those programs, based on different values. the free software movements campaigns for freedom for users of computing; it is a movement for freedom and justice. by contrast, the open-source idea values mainly practical advantages and does not contain for principles. this is why we do not agree with open source, and do not use that term.
