WordPress.org has long been against themes that haven't been licensed under the GPL. So much so that Founder Matt Mullenweg once got into a rather public arguement with Thesis creator, Chris Pearson. Then it was an fight over Pearson not adhering to the GPL. Now Mullenweg is going after developers that use the GPL for WordPress code, and tradional copyright for supporting elements such as CSS and images.

"After I received my ‘notice’ I was invited to chat with Matt Mullenweg about the situation via Skype. His answer:
Matt explained why things are the way they are and why he/they won’t budge on principles. In the end, the conversation had no answers.
Jake: So in my shoes, what would you do?
Matt: as I said earlier, it’s a sucky situation
Jake: But in the short term, the answer is that I just don’t participate and hope for the best?
Matt: I have forgone profit for principles many times and been lucky pretty much every time, but not everyone always is and I can’t speak to other people’s backgrounds or obligations"
