I'm not saying their code isn't shit, just that it is shit code that works (for some purposes at least). That is much different from not being able to generate code that works at all. I would say these guys can "code their way out of a wet paper bag". They will just make a royal mess doing it.
Trust me (as much as you can trust a random guy on the interwebz)... Their code is shit. Not "I'm an artist and think your artistry is shit" shit... but every bad idea you can consider in coding shit.
