The memory that XNU and Darwin are technically open-source projects is a curse that brings one only suffering.

I would call them open access. Apple doesn't accept contributions.

		Does not accepting contributions make you not open source? I would assume if the license allows you to fork it, that makes it open source (as opposed to "shared source" licenses that basically say "look don't touch")
