For me this is really the only value of this list, since it actually address the object of programming, rather than the individual themselves.

Any environment that thinks code is too valuable to change, alter, throw away, simply hasn't got a fully oiled production line going from Design -> Code -> Build -> Use. If there is code too valuable to change because 'nobody understands it' the problem isn't the code, its the people reading it.

But the problem is, people are people, and these days people talk a lot of shit about each other. Its 'normal'. Blame culture infects all human activity, it has been scripted so.
