The point that Stallman, and the article, makes is that both the philosophy and practices of Free Software and Open Source are, in fact, different -- which, arguably, is why Open Source practices have met wide adoption in the industry, to the extent that Free Software philosophy and practices did not. If you disagree, please state how your disagreement sees Stallman's argument (linked elsewhere in the comments) about the difference. Specifically regarding practices: large corporations absolutely did NOT have large-scale software projects in which outsiders could both participate and benefit from via inspection and modification of source code more than 20 years ago. This is what Open Source is really about.
