Some AI generated images can require a lot of tweaking to get a final result. For example, someone might have a workflow that involves generating several images, then picking one as a base. They then take that base, and use img2img to rework certain parts to suit a vision before applying a set of post-processing effects in a traditional editor.
Or, they generate an image and use it as a base for some sort of more traditional art, or use AI generated elements in a work that is otherwise drawn traditionally.
There's a lot of grey where I think just dismissing any creative vision is doing disrespect to the person that wanted to make something out of that vision, and put in a good amount of work outside just proompting and taking the first image that looked okay.
I have a feeling they knew how this would be received considering it seems like they're rage-baiting and acting pretentious to try and get attention.
