What do they release as open source code, apart from TextEdit? I am really surprised by your comparison since it seems to me that the two (bash, vim, top, netcat… and Apple's open source code) do not compare at all.
Apple "owns" LLVM which has changed our computing landscape from the bottom up in more ways than I can count. GCC was happy being stagnant until LLVM came along and GCC could finally see how awful and behind the times they had become. Now there's at least some competition again.
(competition-free platforms are never a good thing, no matter how many times you pray to your zero-to-one god)
