I'm getting downvoted, so I'll expand: If you make ethical judgments directly from the license then Zed Shaw is right. But Martin hadn't really done much wrong. The book was free online, and it would be classed as fair use by many people if it had been made using music, film or tv. He also made sure to credit Zed for the text, and only an idiot would think that Zed was able to change his text to fit the code better so I don't think it would reflect back on Zed badly at all... Then again, in my opinion, what is important is that there are more beginning code examples to read in Ruby. Bullshit over rights or hatred of whole programming communities be damned.
