As per https://xkcd.com/1015/, I suspect many people are doing this and the artists hate all the examples even more than the average consumer who simply treats it as a sign of low-budget work.
My own experiments with ChatGPT's image system is that while I have some pictures I'm very happy with, I also have a surprisingly hard time getting it to follow direction, e.g. shadow direction being inconsistent between foreground and background, making anthropomorphic animals look like they were meant to be (more Elder Scrolls' Khajiit and less big-eyed cartoony fursuits) etc. Stable Diffusion is much easier to deal with in that regard, but then it can't do text and has a much higher frequency of body-horror.
Doing things right is expensive, and most people have no budget. But my guess is people without budget were probably the ones who previously downloaded random pictures off the internet and used them without checking: https://www.theguardian.com/media/2009/jun/11/smith-family-p...
That or perhaps even use pirated versions of Photoshop.
