Re: Are all files produced by GPL Ghostscript copyrighted by 'Artifex Software, Inc.'?
One solution to the problem is to get the source code, delete the lines which insert the copyright notice (“modify the code”), compile the code, and use this. This is legal as the code is released under GPL and GPL allows modifications. (You could release your modifications too. This is how Debian makes ‘Iceweasel’ out of ‘Firefox’ -- just so that Debian users don't have to sign a EULA with Mozilla.)
Still, Ghostscript (in its present state) should not be a part of Debian. Indeed, if signing a EULA is unacceptable, how much worse is having your code copyrighted by a third party!
