The guy states that he wants to make some kind of buck, quick or otherwise, from having his work used. Since it was used on a project that probably makes lots of bucks, and since the graphic probably contributes positively to the marketing and success of said buck-making, that seems reasonable. I shouldn't put words in the parent commenter's mouth, but it sounded to me like "Stuff like this happens all the time" was just acknowledging reality, not judging right or wrong. Also perhaps indicating (but if they weren't then I am now) that hiring a lawyer is not actually this drastic, horrible outrage to be avoided at all costs, but a rather routine measure advisable for anyone in business for themselves or anyone facing an obviously legal issue such as copyright infringement. Since this seems a pretty clear case, chances are good that he'd get his legal fees paid too, meaning the lawyer is free.
