"The Sony rootkit case made it quite clear why DRM is not accepted by consumers and why there is no successful business case for DRM," he said in an e-mail. "Apple iTunes allows people to burn their tracks on regular CDs, which can then be re-encoded and file-shared easily--so is better described as 'digital inconvenience management' only. eMusic.com offers clean audio tracks without any restrictions. No DRM platform comes close to either of these in popularity."
