If a central entity owns enough copyrights, what's to prevent someone from coming up with a bogus lawsuit-defamation, slipped on the ice on their front steps, whatever-getting a multi-million dollar judgment, seizing their assets, and making the whole shooting match their own personal property to use however they will ? ( except, grudgingly, recognizing the remaining GPL licensed stuff as beyond their reach ) Nor do I think that Wikipedia, contributors being such as they are, should really be beating down the doors to get into a courtroom!
