I do research for a private company, and open-source as much of my work as I can. It's always a fight. So I'll take their side for the moment.

Many years ago, a paper on the PageRank algorithm was written, and the code behind that paper was monetized to unprecedented levels. Should computer science journals also require working proof of concept code, even if that discourages companies from sharing their results; even if it prevents students from monetizing the fruits of their research?
