I'm a staunch pro-commercial use freebie person. I mean, if its free, it should be free. Non-commercial use means only "half-free" - lol. I do agree that trademarked stuff, i.e. a particular superhero like Superman or what have you, should be for non-commercial use only, UNLESS DC Comics states specifically that you can sell a certain image of their character, etc. I don't download no-commercial use items, and if I do, and the readme doesn't allow for commercial use, it doesn't get installed and it is doomed to the recycle bin - unless it is stuff like Superman/Darth Vader, then it goes in my "No Commerce" foldr, for fun pictures.
