Apple vs. Real is not the same thing as 3rd Party Toner Makers vs. Lexmark or DVD John.
It would only be the same if Lexmark's printers already had open-compatible ways for 3rd party toner cart makers to sell toner cartridges that end users could put in their printers. And DVD Jon would have to have made a DVD burning app that let you create CSS DVDs with regional encoding.
The iPod supports AIFF, MP3, AAC, Apple-Lossless all unencumbered with DRM. Real isn't trying to get music on the iPod. Real is trying to make locks that match Apple's keys.
This is a very different issue, and I don't know how I feel about it. This actually is much more akin to a hacker trying to spoof a message's source than the slashdot community seems to want to acknowledge.
