How do you listen to him after gems like this: "Free Software supports education, proprietary software forbids education"?
You know what? I got my education without software free or proprietary. I also saw many getting education and knowledge using proprietary software. Does Internet Explorer ban you from going to wikipedia or coursera? Heck, I even educated myself about free and open source software using Windows.
Model of the world where FOSS is at the center of the universe and rms is the brightest star in it is hardly correct.
