"closed source is necessarily and fundamentally immoral, nay, evil" Keep in mind that RMS is talking about the broader social impact of a proprietary software ecosystem, not any single proprietary software product. RMS is working against a model where people are divided by the restrictions imposed by proprietary licenses and by proprietary software itself. In a proprietary software ecosystem, people are divided not merely by their technical skills, but by the whims of software vendors. The reason RMS' arguments seem to have implications outside the field of software is that proprietary software ecosystems have effects that go beyond software.
