The “cult” thing might make sense if there were any history at all of GM, or really even any auto maker, making a better infotainment system than CarPlay. But it’s never happened. Imagine GM were a home builder who suddenly said they will no longer sell any homes they build, only rent them out. You are free to sell your house with your 3% mortgage, and go back to renting, to see if you prefer it. But those who choose to continue owning are not in a “cult,” and they’d think you were making a pretty bad decision. And they’d almost certainly be right.
