You are suggesting that he give screenshots of copyrighted software a CC license? ....Right.
How is that different from say, a CC licensed photograph of a car or an iPhone?

A screenshot is a document like a photograph or essay or article; it's not a physical object. Cars and iPhones are not copyrighted. Software and software UIs and documents mechanically reproducing them are.
Tell me, do you think the copyright on the text in a software UI just magically goes away because it's a screenshot? How about the icons? Or the fonts? Or any images? What if the software is displaying a photograph or book? Did you just discover a way to make anything under the sun public domain? (An amazing discovery!)
Tell me, do you and all your upvoters think you know better than Wikimedia Commons when it writes (http://commons.wikimedia.org/wiki/Commons:Screenshots) :
> Screenshots are subject to the copyright of the displayed work, may it be a video, television program, or a computer program.
Do you think you know better than the librarian who wrote http://web.archive.org/web/20080216021841/http://www.jiscleg... ? Or how about http://www.chillingeffects.org/copyright/faq.cgi#QID809 or http://lifehacker.com/193343/ask-the-law-geek--is-publishing... or any of a dozen links you could have found in seconds googling 'copyright screenshot'? Notice the only question is whether fair use will defend you when you infringe on copyright by making screenshots and not whether screenshots are copyrighted at all, because they are copyrighted.
Do you, in fact, have the slightest argument besides a specious analogy?
