This is a policy issue which should be discussed on wikipedia-l, not on wikitech-l.
But, basically, I remain firmly opposed to the mixing of non-GFDL material into the encyclopedia as a matter of principle.
I believe that this is to appease the forces that be so that they will have confidence in turning wikipedia into a marketable, paper product.
Well, I'm "the forces that be", and <sarcasm>yes, you're right, it's all a scam to make money</sarcasm>. :-)
