Complying with copyright is not a great example of "Open Source history"

[Argorak → _optl]

Apple has funded clang and LLVM, maintains CUPS, funded MacRuby for a while and packaged a lot of OS Software for their system, promoting it.

Not all is gold, but that's certainly more than "complying with copyright".

At least the first four in the OS X 10.10 tree are apple original software, not just source dumps of other people's OSS products. Ok, that's terrible statistics since the files are alphabetized and Apple comes early. But take a look through there at the copyright owners and you'll see lots of original software released as open source.

Complying with copyright is the entire premise of copyleft aka the GPL.
