Don't be ridiculous. That does not make "You are doing god's work, son. Thank you." any less ad hominem, nor do you actually demonstrate any reasons. Your argument amounts to "copy+paste coding is bad, therefore your codebase is bad", yet at no point explains why. But keep downvoting anyone who points that out :)

An ad hominem argument is one in which you reject a position not on its merits but because of who is making it. They took a position that copy/pasting code leads to unmaintainable code, therefore his argument is not ad hominem.

He's being insulting, sure, but that doesn't mean he's making an ad hominem argument.

It is ad hominem. The ad hominem part is the part which infers the parent poster makes whole teams grind to a halt and also earns less than himself.
