In "How to avoid code review comments that add no value?" I answer a programming question.

Think of it this way. Your car doesn't work engine isn't running. Along comes Tom and says the car needs a wash. Tom's an idiot. His input won't get the car running and he is ignoring the problem at hand. Tom just wants to be useful he doesn't know how. Tom should learn to keep his mouth shut. Everyone knows the car needs washing. That isn't the priority at present.

Code Cosmetics are low value. 99% of the time someone complains about code readability it is a skill issue on their part. You can hand over high performant code to people and a short while later hear how they are having trouble and when you check into it you find someone has tried implementing "clean code" something else they don't understand and get wrong more often than right.
So what was your code looks nothing like nor does it perform correctly. Which is why one puts clauses in contracts that you are no longer responsible for the code if it is modified. If they want it fixed again I charge them again for it.
