You stated: "If code is not maintainable who cares if it works. If code is maintainable it can be made work, if it does not."

So who cares if code that doesn't work is maintainable, if it's not maintainable by them? I buy a close-source program, I find it doesn't work, I write the user support and they never answer - why should I care if the original source code is maintainable?

Who cares if it's maintainable if it works for them, but they don't have access to the source? I buy a program. It works. I have no idea if it was a single shot programmer luck or result of long-term clean code policy. I don't care.

But who DOES care about code maintainablity? Well, first off, your boss. Management loves to have maintainable code, because then they can fire developers at will and the new ones blend almost seamlessly into the development process. No need for raises, bonuses or such, just replace whoever complains. And the second in order are the developers, because maintainable code is, well, easier to maintain. And writing unmaintainable code in order to secure your work position is considered unethical.

Oh well, maybe by NOT "the most important feature of a program is that it is mainatainable by Bartosz Wucke" you meant "the most important feature of a program is that it is mainatainable by ME and ONLY ME"?
