And I think that's where the confusion is. CarPlay doesn't "run on" QNX in the sense that QNX is the platform Apple chose to implement CarPlay. It's accurate to say iCloud "runs on" Azure, as the iCloud platform, at least partially, runs on Microsoft's Azure services. The QNX OS implements the car portion of the CarPlay protocol. Other OSes can also implement the car portion. CarPlay is a protocol, not software that runs on anything.
