I know the image, what I do not understand is the argument between using it being incompatible with "fairness" and "openness"

I can't speak for the other commenter, but I think companies like Midjourney and OpenAI are robber barons exploiting people's creative work in ways that obviously aren't fair, but that our legal system wasn't equipped to prevent.

GenAI image generation is not fair.
