Following up on this earlier BoingBoing post, reader Francis Hwang says,
On Tuesday, November 30, I offered the "Unauthorized iPod U2 vs. Negativland Special Edition" for sale on eBay. On Monday, December 6, only one day before the auction was scheduled to close, I was notified by eBay that my auction listing was being shut down at Apple's request. Apple had told eBay that my work was in violation of their intellectual property rights. I have emailed Apple asking for an explanation, and am waiting for a response.
