Oh, please, spare us!
If you're going to use a metaphor, try to pick one that obliquely applies to the actual situation at hand. Putting diesel into a gasoline/petrol engine (or vice versa) is hardly the same as putting a 3rd-party touchscreen on an Apple device. A more apt metaphor might be that if you change your oil at home by yourself, you will get the little "engine warning" light to come on if you don't also reset the counter for it. Now if the engine warning light coming on were to also summarily kill the engine, lock all the doors of the car, engage the emergency brakes and fire the airbags, I think there would be some rather pissed off people (assuming they survived the inevitable crash that would result when that occurs on an Interstate), and those pissed off people would own GM from the proceeds of the lawsuits that would follow.
(P.S. Putting sugar into the tank of either a gasoline or diesel car would equally screw the engine. If we had some kind of electronic sensor preventing the engine from running if it detected sugar....)
