My viewpoint is coming from "just don't be an asshole." The author has every right to be upset, and he should seek monetary compensation for the use of his work. However, he didn't have to come out and publicly criticize Naughty Dog, especially before contacting them. Like I've said in other comments, Naughty Dog might seem like a large company, but I'm sure it was just one person who decided to use that picture, and probably didn't know the rules/laws around using that kind of imagery. In fact, it was likely an intern put to the task. So, in reality, the author is shaming some poor bastard who works at Naughty Dog and they made a mistake. My viewpoint would have been to contact them and say: "Hey guys, noticed you used one of the maps that I made. I appreciate the fact that you guys liked the design of the map enough to incorporate it in your game, however it is protected by copyright. Seeing as this is probably an honest mistake made by some new person you guys hired (obviously), I will not publicly flame you guys on my blog. I am only seeking $XXXX for the use of my work. Thank you, and have a nice day."
