First, please watch your language...
Second, this is off topic from the NPO announcement, since the license has NOTHING to do with the corporate structure.
However, that being said: GPL is a bad license. We will not be GPL. I have already said this.
Joomla, because of the way they have coded/licensed previous code, can not grant exceptions to their GPL (as many others have done)... which means that it is unlikely that there will be an official Joomla bridge.
Do remember that Joomla is not the be-all and end-all of CMS.
