One of the arguments of ClosedSource proponents is that 99% (or some suitably overwhelming proportion) of users have no desire to see source code, and no ability to do anything with it if they could. Therefore the claimed advantage of OpenSource in allowing such things is pointless.
RedHat's Bob Young points out that exactly the same thing applies to cars: 99% of car owners (and drivers) have no idea what is under the bonnet of their car, no wish to look at it, and no ability to understand or modify any of the mechanisms there. Therefore, by the same logic, why bother to build cars with a bonnet that can open at all: why not seal the bonnet, and the customers will be just as happy, right?
