Perhaps you could explain to us what those legal and ethical concerns are? It might help us understand why our work has been disqualified, Because legally, I've made sure that the images I produce belong to me and me alone and I am free to do what I wish with them, commercially or otherwise.
For legal reasons in the United States you cannot copyright AI images: Link , Link
There are also issues with artist having their work taken without their permission to use to train the AI, which I believe is unethical and shouldn't be legal. You can read more about it here: Link
AI has also been found to use private medical photos in their generators Link
Thank you for understanding
