If you charged money, that's something people can relate to. People understand the need to put food on the table. People even understand that jet skis are a lot of fun but they're not cheap. Money makes the world go around. So you could charge away with the full approval of every capitalist in the room.

But it's disappointing to see people hoarding knowledge in order to feel important. Guess what: there are nearly seven billion other people out there. A lot of them are smarter than you, at least in some way, no matter who you are. I'll bet that somewhere in those seven billion people, there is someone who could take your research and produce a product better than yours. (No insult intended -- the numbers are just against you.) If you only released the source. So you're holding the world back in order to feel good about yourself. It's still a relatable concept, but now it's a low, dark thing, and no longer morally defensible.
