NOTE

Without a doubt, GNU/Linux (and every other distribution, including Red Hat) owes much of its success to Richard Stallman, the Free Software Foundation, and the GNU General Public License. Without the freedom to freely distribute software in source code form, and the ability to make and share changes, Linux may not have spread and improved as quickly as it did over the Internet.

This appendix contains a copy of the GNU General Public License. However, you should know there are many different types of software licenses used by software available for Linux. These licenses cover a broad range, such as the BSD-style license, a public domain license, an Artistic License, and restrictive proprietary licensing.
