There are design decisions that are wrong. Invisible emergency exit signs are a wrong design decision. Making the emergency off button the same color and shape as the light switch is also a wrong design decision. And yes, I think the original problem is also a wrong design decision. Design isn't just art, design of functional objects needs to be functional. That means that there is an objective criterion for wrong design: if it isn't functional, it's wrong.
