Sure, but what I'm missing is a support for these claims. Using != supporting is true by it self, but to what extent is that practiced in Apple's case specifically? It's still just a claim with no supportive argument at all. Some projects that Apple supports and contributes/has contributed to that comes to mind, launchd, libdispatch, ALAC, OpenCL, LLVM, Quicktime streming server, and Webkit to name a few.
