Please re-read my parent comment. A few weeks after Apple announced Metal at WWDC Khronos members met for the first time ever to kickoff then project to replace OpenGL. I don't believe that is a coincidence. Maybe Metal was the straw that broke the Camel's back, maybe not.
I also noted that AMD donated Mantle as the starting point which is why Vulkan didn't take 5 years to finalize.
In any case claiming that Apple is somehow at fault for not adopting Vulkan doesn't make sense.
I just said that it's severely overstating the case.

Why not? They could have adopted Mantle instead, for example. It came out a year earlier. Or it could have replaced Metal with Vulkan later (as it is often a reasonable choice to replace your custom solution with the industry's standard). Or it could have chosen to officially support Vulkan alongside it.
Apple has lots of money in the bank, and with that, lots of options.
That seems to give way too little credit to Mantle. Which was released in 2013 and became the basis for Vulkan.
