It's the GCC and the related tools, my friend, that made possible the GNU Linux OS and its kernel, and a multitude of other open source (free!) software. And also the GPL license, of course.

People shouldn't be so fixed just on Emacs as the only Stallman's contribution and defining legacy in the software world. IMHO, his editor is the least important thing he created.
