Your reply says it’s not rude it’s factual, and you defend it as factual by saying easy/hard is subjective with the skill of the developer (i.e. not factual), and you defend that it’s not rude by insulting the dev skills and calling them mediocre and laughable? And you don’t address the bit where he storms off in a huff when much less is said back to him? Even if I agree it’s factually easy, walking up to someone and saying “walking is easy if you’re not a cripple, am I missing something?” is rude if the person is disabled and even more rude if they aren’t. “But they’re crippled! Fact!” doesn’t make it not-rude behaviour. He isn’t Linus Torvalds and even LT insulted devs on behalf of userland and good code and not just to make himself feel superior. And doesn’t have an eggshell thin skin.
