Cynical Sony.

Sony’s NetMD minidisc players require a piece of software called OpenMG before you can transfer MP3 files to them. Despite the “open” name, it’s far from open in any sense of the word. The software isn’t available for download anywhere. It’s got a draconian digital rights management scheme built into it. And Sony has aggressively pursued Web sites that have sought to provide alternatives. No wonder minidiscs never caught on.
