No, I'm not displaying parts of the codebase. But I'm displaying
documents that are derivatives of that codebase. For instance n a
typical web page I'm going to include some graphics images, a CSS file
the page is going to include large sections of templates that were in
the codebase. Much if not all of this is copyrightable information.
All that the GPL says on this topic is that "the output from the
Program is covered only if its contents constitute a work based on the
Program". I'm claiming that the output that is delivered constitutes
a work based on the Program.
Note that similar issues have come up in the case of gcc, and I have
heard that there are optimizations that have not been made because if
they were, then the compiled output from gcc would have to be GPLed.
