As a car owner, I should have the freedom to open my car, inspect its inner workings, change/fix things as desired, and share my knowledge others. The ability to openly inspect the inner workings also allows me to assure that the car is only performing operations I purchased it to perform.
However, as a car developer, I cannot possibly hope to make money by giving the car away for free. There have been significant hours invested into the design of the car. Sure, there's money to made in maintenance, but realistically most people don't care about routine maintenance. They'd rather buy the car and ride it 'til the wheels fall off - maybe an oil change here and there.
Are these two views fundamentally incompatible? Does anyone pay an upfront cost for free software in recognition of the time spent building/designing the product as they might with proprietary?
