"It was the perfect opportunity to leapfrog Google and help the open source community"

The only time Apple helps open source is when they hire the most important people in really important projects, and then they graciously allow them to continue contributing. CUPS, LLVM, it's happened a couple times. They take good care of these guys, but I always feel like their contributions to the projects after Apple are being written with one eye watching over their shoulder to make sure they dont get sued for talking to the public about some super secret project.
