An iPhone port of GNU Go is currently being distributed through Apple's App Store. However, this distribution is not in compliance with the GNU GPL. The primary problem is that Apple imposes numerous legal restrictions on use and distribution of GNU Go through the iTunes Store Terms of Service, which is forbidden by section 6 of GPLv2.

GPL enforcement is successful in Europe. In several court decisions and out of court settlements the license conditions of the GPL have been successfully enforced. In particular, embedded systems are the main focus of such compliance activities. The article describes the practice of enforcement activities and the legal prerequisites under the application of German law.

Combining freedoms and copyleft in the Gnu GPL license (invented by Richard Stallman) was the cornerstone of free software. This is now questioned due to the proliferation of incompatible copyleft licenses.

New heights for Microsoft's spin and lies; the latest wave of GPL smears arrives from friends of Microsoft and former employees

Richard Stallman's willingness to accept the sale of exceptions to the GNU General Public License intrigues me. What intrigues me is not his acceptance of the idea. Rather, what fascinates me is how many people are reacting as if his comments are something new.

The practice of selling license exceptions became a hot topic when I co-signed Knowledge Ecology International's letter warning that Oracle's purchase of MySQL (plus the rest of Sun) might not be good for MySQL. As the following article explains, my feelings about selling license exceptions are mixed. Clearly it is possible to develop powerful and complex software packages under the GNU GPL without selling exceptions, and we do this. MySQL can be developed this way too. However, selling exceptions has been used by MySQL developers. Who should decide whether to continue this?

Would you like to see some places where Caldera has copyright notices in Linux on code it contributed under the GPL, and you're frustrated because some of us have Caldera CDs and you don't? Just go to Google code search and search forlicense:gpl "caldera.com" You'll be buried in GPL'd Caldera code, 5,000 hits.

A reader sends us some more screenshots of Caldera, now SCO Group, distributing header files under the GPL. This time, it's from OpenLinux 2.2-4, dated from 1999.
