This is uncharitable. The GP's comment is short. What people have an opinion about is, "Give up on 'good code'" and, "working code, code that pays the bills ... code you can throw away easily, code that you are wholly unattached to".
big claims require big justifications. I can't just go out and say "C++ is better than Javascript" and expect people to not scrutinize me because "well it was a short comment".
But hey, they do justify it in responses. So maybe they are indeed playing to their philosophy of "work fast"
