if something happened to them, I don't doubt that they'd just throw all of it out there.
OS X, OS 9, parts of Copland, Rhapsody, any parts of Taligent that are left, Quicktime, all of it would go open source.
They'd do it just to undermine MS. And I think it would go far beyond undermining them. It would mean that even without Apple, the Mac would still live. People could buy PPC mainboards and run OS X (or OS 9 if they were inclined) because the OS could be adapted for new boards not built by Apple.
The Mac would then be the "open computer"... even more than PCs. And MS would face the beginning of the end at last!
