Why Open Source is not in Government more than it is

Business systems are built around ensuring that people pay for what they use - and if something fails to perform they can be taken to court and made to pay for that failure. With Open Source there IS NO WAY TO enforce payment for failure to live up to promises since NO ONE person or firm owns the code - no one to sue. Imagine a group of people all getting together and building a car then giving it away. If a tire falls off and the person driving it gets killed and none of the builders can EVER be held responsible would you buy use car knowing that if anything breaks its YOUR fault and no one can pay for the faulty assemblage of it?
Open source is like that car - if it causes you problems there is no one to blame and you just have to live with it. To continue the car example you can ask the person who bolted on the wheel how they did it, but they may or may not respond, even be findable, and may not help you if you discover the problem before it fell off - since they just helped its not their problem and they are NOT making any living off of perpetually helping people.
The government ALWAYS insists that the firm be held accountable and payable for bad products - which is the main reason Open Source has not been fielded in any meaningful way - if it fails to work as designed no way can any money be recovered for lost time in trying to use it or people be forced to pay in rebuilding destroyed data, or other problems caused by using it. There is no liability trail at all. The lawyers will hate it! <:)
