There's faults on both sides. The guy is clearly in the wrong by failing to follow the copyright restrictions, but it was probably an honest mistake. Since he's spending to much time on the book, he's probably a fan of Zed's work. And he may be thinking he's adding value to the book. On the other side, Zed was completely within his rights to ask the guy to take repository down, but didn't need to make any assumptions about the guy's intentions or "class".
