Activists have bypassed restrictions set on Apple's iTunes Music Store in less than 48 hours. This allows customers to play music downloaded from the site on any platform, not just Mac or Windows, thus increasing Apple's potential customer base. The downloaded music is not protected by DRM, so it is also vulnerable to illegal copying.
DRM has proved unpopular with many consumers because, in addition to protecting the content from illegal copying, it restricts the customer unfairly: dictating what equipment they must use and preventing permissible "fair use".
