Could not disagree more. The author most probably freed the company from its dysfunctional stagnation due to some political issue. It is thanks to his ignorance that he resolved an issue, something that had to be done.

In general, staying out of other people code is a bad idea. It promotes lack of transparency and agenda proliferation. This is because the owners of the code start being a "monopoly", can work less hard, provide exaggerated estimates etc. When people know that others can read there code, maybe hack on it, make something faster or simpler -- well they work harder and tend to be more transparent.
