You are right, of course. But I will have to maintain my point that they do not know these tricks. I have worked with these people, and I know. They hire the help, and most can't afford to do so to satisfy a simple curiousity. Not only that, but most of the site has been built in photoshop, with most of its text contained in graphics, which defeats any basic users attempt to highlight, then copy the text. With the addition of disabling the source button it should give him some relief.
