The case has been brewing for years, but was only recently approved to move forward for a jury trial. The plaintiff's lawyers (who represent a class of customers affected by the accusations) argue that Apple used FairPlay to forcefully "lock in" customers to its own ecosystem by making it difficult for them to jump ship to another platform. Real Network's music store (circa 2004) is repeatedly used as an example: updates to Apple FairPlay consistently blocked songs purchased on RealPlayer from being transferred to iPods. This system also limited where songs purchased on iTunes could be played -- if someone wanted to switch out of Apple's ecosystem, they'd have to re-buy all their old music.
The sum, the plaintiffs argue, is that Apple intentionally made it difficult for its customers to leave its ecosystem, bolstering its own monopoly in portable music players and violating anti-trust laws. Apple says there's no evidence that its decade-old squabble with Real had any notable effect on iPod pricing or dominance, pointing out that Real only cornered a mere 3-percent of the market at the time. It's an interesting argument, but it wasn't enough to stop the trial from moving forward. Apple's old DRM will have its day in court on November 17th.
