News and commentary that the new Office XML formats are not compatible with the GNU General Public License - and therefore not 'open' - prompts Microsoft's Dare Obasanjo to respond:

"There are two points I'd like to make here. The first is that "being GPL compatible" isn't a definition of 'open' that I've ever heard anyone make. It isn't even the definition of Open Source or Free Software (as in speech). Heck, even the GNU website has a long list of Open Source licenses that are incompatible with the GPL. You'll notice that this list includes the original BSD license, the Apache license, the Zope license, and the Mozilla public license. I doubt that EWeek will be writing articles about how Apache and Mozilla are not 'open' because they aren't GPL compatible."
