This makes sense. However, if the code 1) is hard to understand (according to the developers available) and change and 2) needs to be changed, it costs money.

Eg, read about the expense banks are now incurring trying to maintain COBOL systems. Whether the code is "bad" is debatable. But the fact is that they have a hard time finding people who can work on it.
