I understand where you're coming from, but the only reason the source is available here is that he wrote in client-side JavaScript. There is no link to the source, no download, no indication that the source is meant to be available, and the explicit invitation to interact with it is to play the game, not monkey with the source. You make it sound like he was exhibiting the code just because he didn't make it impossible to see.
