Please, tell us all about how Khronos hurt Apple with free software that Apple had every opportunity to influence. Point to the boo-boo that justifies making things worse for everyone.
I can imagine a scenario: Apple donates openCL, then later suggests some changes for the next version. Khronos delays or pushes back and now openCL is stuck from Apple's perspective and they can't do anything about it.
Where are those great OpenCL implementations from Intel, AMD and Google?
