The suit alleges that: "Apple has engaged in tying and monopolising behaviour, placing unneeded and unjustifiable technological restrictions on its most popular products in an effort to restrict consumer choice, and to restrain what little remains of its competition in the digital music markets."
According to the complaint, "Apple's crippleware operating system software prevents the iPod Shuffle from playing WMA files. Apple's iPod is alone among mass-market Digital Music Players in not supporting the WMA format,".
This time, the claims are predicated on the increasingly outmoded view that rights owners "are generally unwilling to license their music for online sale except in protected formats". Amazon now carries unlocked MP3s from three of the four major labels, along with hundreds of independents.
