Rich Bowen mentioned this little “feud” in a short post on his Web site. According to the GNU web site, the Apache Software License version 2.0 (ASL 2.0) is listed as being incompatible with the GPL. Apache claims they have no clue where this comes from, and they stand by their belief that the ASL 2.0 is, in fact, compatible with the GPL. Apparently, it is believed that Slashdot may be fueling this “inaccurate” perception.
If the ASL 2.0 is compatible with the GPL, then there would be no need to include the aforementioned exception when including ASL 2.0 code in your GPL’ed applications.
