Getting shocked by my defibrillator unnecessarily while pregnant (once I had time to process it) really stands for the proposition that our technology may not be made for our situation, despite the best of intentions by manufacturers. Things change, companies go out of business. Having access to the complete and corresponding source code (and the scripts to control compilation and installation) is a basic part of integrity in our critical technology.
