History
The license was derived from the GNU General Public License, but differs on two key points:
- The source code must be included with any software distribution.
- The software may not be sold, including any fees involved with distribution.
Deutsch chose to include a commercial restriction in the AFPL based on his observation of people including Ghostscript in commercial products without full license compliance.[2] Recent versions of Ghostscript are not licensed under the AFPL.[3]
Despite the name, the Free Software Foundation does not consider the AFPL a free software license,[1] neither the OSI consider it an open-source license, nor does it fall under the Copyfree Standard definition.[4] The AFPL can be considered a source-available license.
