The Aladdin Free Public License (AFPL) is a license written by L. Peter Deutsch for his Ghostscript PostScript language interpreter.
The license was derived from the GNU General Public License, but differs on two key points:
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. Recent versions of Ghostscript are not licensed under the AFPL.
Despite the name, the Free Software Foundation does not consider the AFPL a free software license, neither the OSI consider it an open-source license, nor does it fall under the Copyfree Standard definition. The AFPL can be considered a source-available license.
As you recall, I promised Stallman that I would continue to distribute Ghostscript with the GNU license. But I saw a number of companies bundling Ghostscript with commercial products while just barely complying with the letter of the GNU license, so I decided that I did not want to make Ghostscript as available for commercial distribution as it would be with the GNU license.
