With an open system, that flaw would have been detected way earlier. Now the original post was about closed hardware, so I'm not sure if this was the case here.

I have never tried flashing some motor control of a car, but it's possibly not even restricted, so "open system" would more likely refer to "open source". While there might be an incentive to restrict modifications (at least on a car, which is potentially dangerous), I don't see counterpoints to open-sourceing the software that runs on (the car in this example).
