If you criticize the code by pointing out factual issues, then the the author can lean and improve by understanding these issues and improving the code. Calling the author an idiot does not help to improve anybody.
Hence denying the author the possibility to improve. Eventually the author will be let go, and they will have no idea why or what they did wrong.
This is called "being polite."
