It seems like you're trying to catch this guy out for cognitive dissonance but I'm not seeing it.

CarPlay is offered in perfectly functional forms in the market right now for a reasonable upfront price that people will pay for a known feature set.

A subscription arguably can make the product less valuable, because of uncertainty about continuing support, changes to the subscription model or software, and an unknown price that will likely end up being higher than the flat fee offered by competitors.

This isn't cognitive dissonance, it's worry that BMW might pull a bait and switch.
