Why do I want to make money from my hard work? Or why am I sad when someone offers a way to bypass paying money for hard work to get something for free?
I meant that the author of DragonRuby is generous. And depending on your use case he might be willing to give you a free copy. Additionally, whenever there is a gamejam related to DragonRuby, he usually gives away free copies to anyone who wants to participate. For you to keep. Nobody said anything about bypassing paying money. Not sure what you were thinking.
