I don't understand why people say things that are kind of trivial to disprove, but here's the document with the notes where Apple refuses to use SPIR-V.

> MS: Apple is not comfortable working under Khronos IP framework, because of dispute between Apple Legal & Khronos which is private. Can’t talk about the substance of this dispute. Can’t make any statement for Apple to agree to Khronos IP framework. So we’re discussing, what if we don’t fork? We can’t say whether we’re (Apple) happy with that.

Reading between the lines, it seems like Apple mainly doesn't want to implement SPIR-V because engaging with the "Khronos IP framework" would prevent them from suing other Khronos members over patent disputes.
