It's a video game, not a work of art. It's meant to entertain you, not enlighten you. The very basis of your "principle" is flawed. Some of you people are out here living in your own little fantasy worlds, thinking everyone else need to do the maximum amount of effort and sacrifice just to make you happy. If an indie dev can't afford something and uses AI for it, then so be it. It's for the dev to gain some coding experience to be able make better games in the future, not to waste massive amounts of money and time just to make a very small group of people happy.
