There was a time when Apple would use open source (and this website) as a marketing tool. Probably back in the Tiger/Leopard days. And they used to contribute their userland fixes to upstream BSD too. These days Apple doesn’t seem as committed to open sourcing of its core OS software as it once did.
Did they not need to update the Copyright Date? Still only 2012.
They have confusing places, opensource.apple.com and Apple.com/Opensources are two completely different page with different content.
It just shows Apple really couldn't care much about it.
Why cant they have a single Page that shows everything they use and release in a nice beautiful way.
