I don't know about anyone else, but I for one would not purchase anything that wasn't royalty free, if you can only use it for personal use you might as well get something from freestuff. What does concern me though is if I was led to believe the product was royalty free, only to discover after purchasing it and downloading it that it had a further licence document saying that it wasn't royalt free. I think I would feel, fairly, that I had been decieved. Would it not be far simpler to display each products licence so we can all see what we are getting.
