Defendant's most significant present challenger in the Intel-compatible PC operating systems market is the collection of &ldquo;free software,&rdquo; which is free in the sense of freedom, not necessarily in price: thousands of programs written collaboratively by individuals and organizations throughout the world, and made available under license terms that allow everyone to freely use, copy, modify and redistribute all the program code. That free software, most of it licensed under the terms of the Free Software Foundation's GNU General Public License (&ldquo;the GPL&rdquo;) represents both an operating system, known as GNU, and an enormous corpus of applications programs that can run on almost all existing architectures of digital computers, including Intel-compatible PCs.
