they knew exactly what they were buying. Why am I reminded of a scene from Airplane! here? The average person probably doesn't even know what "the cloud" is beyond the name of a product or two. They know that they can push a button their phone and turn the lights off. You imply a level of knowing and care that most people do not have, and so one that is not realistic, or reasonable to expect.
