This story is nice creative writing, but didn't anyone read Steve Jobs letter about releasing DRM Free music. The last thing he would do is put anything in the file that could be seen as copy protection. Besides that, the LAST THING Jobs would want to do after calling for the end of DRM, would be have Apple act as a police state for the record industry. Look to the RIAA for the source of this idiotic story.
The usage agreement, as I read it, specifically states that iTunes Plus songs do not contain any security devices. End of story... here's the quote from the usage agreement:
b. Use of Products. You acknowledge that Products (other than the iTunes Plus Products) contain security technology that limits your usage of Products to the following Usage Rules, and, whether or not Products are limited by security technology, you agree to use Products in compliance with the applicable Usage Rules.
