My guess is from the "cheapness" association. AI generated images and video are used a lot in scams, really cheap and bad marketing, waste of time clickb8 videos and stories etc. I can't speak for everyone but my brain associates it with that and when I see AI tells my immediate thought goes: "is this trying to lie/cheat me in some way, did they really put in effort and care in this?". Code is more opaque, an ugly unmaintainable mess can still create a decently functioning game experience from the player's pov. There's infamous examples of some very shitty code still resulting in games people adore. Ultimately your point stands, if the product is genuinely good and appeals to people, they will like to buy it and play it no matter how the sausage was actually made. AI generation just ruins the signal though, it's tougher to find the jewels among the sea of slop and that'll affect how consumers judge your product.
