I agree that free and open source is the only way forward.
However, RMS is quite extreme. He once told Bryan Lunduke on Linux Action Show that his children should starve instead of Bryan working on proprietary code.
He also believes necrophilia is a harmless crime and that it's immoral to have children as they a large cost of global warming. And let's not forget he didn't think there was anything wrong with child sex thing, though he did apologize and later state he wasn't versed on the science that shows major harm can be done mentally and emotionally from it. Not defending him in the least in this, just stating he apologized.
I'm not saying this to say he's a terrible person, he's not. But he's a person and we need to remember to never put anyone on a pedastal as everyone has something we won't agree with.
