Throwaway, because I'm pretty sure I will be exorcised for this but.. I've never seen a situation where any of my contributions to open source have provided me with the least amount of income. If an author doesn't want to open-source his code, I don't see the big deal.

I suppose the HN crowd that legitimately wants to read code, but the majority of the people are going to go to the trouble are going to be programmers who are being whipped mercilessly to build some 3rd rate web app for their corporate masters, or competitors who want to improve their own technology.

BTW: Can you link the license page? I am looking for it, but can't find anything.

(Mind you: I do think the author is somewhat insane and sounds like almost every bitter 1980s programmer I ever met - but I'd like to see the insane conditions he imposes)
