To defend my position: They're not calling it a "crown", they're calling it a "digital crown", and digital knobs are common place objects that already have a name.

If I build a car with a joystick instead of a steering wheel and call it a "digital steering wheel" everyone would say, "No, somebody invented that already, it's called a 'joystick'"... they would not say "I am going to educate the uninformed and tell them that among car connoisseurs, a joystick is called a steering wheel."
