If product owners are given the ability, they will gladly retune the engine software to output more power, and defeat aftertreatment systems, both to the breaking of emissions laws, and the detriment to the environment. It's a tricky business trying to lock down only parts of the software. Once the cat is out of the bag, all bets are off, to mix my metaphors, so manufacturers err on the side of caution. It's not PURELY to screw the customer. ;-)
