Tensions are already high over Novell's patent agreement with Microsoft, but Ubuntu founder Mark Shuttleworth's invitation to openSUSE developers “concerned about the long term consequences” has kicked the tension up a notch.

Shuttleworth sent an email to the openSUSE developer's list, reading in part:

Novell’s decision to go to great lengths to circumvent the patent framework clearly articulated in the GPL has sent shockwaves through the community. If you are an OpenSUSE developer who is concerned about the long term consequences of this pact, you may be interested in some of the events happening next week as part of the Ubuntu Open Week:

…I know that posting this message to an OpenSUSE list will be controversial. I'm greatly respectful of the long tradition of excellence in the SuSE product and community and have no desire to undermine that with this post. That said, I think the position taken by Novell leadership in their contract with Microsoft is hugely disrespectful of the contributions of thousands of GPL programmers and contributors to SuSE, and I know that many are looking for a new place to get involved that is not subject to the same arbitrary executive intervention. Ubuntu is one option, as are Gentoo, Debian and other communities. Please accept this mail in that spirit.
