By that logic most media consumption is unethical. Almost anything out of a major studio is made with the abuse of, underpayment of, and often even outright theft from small artists. I think a much better solution than not using them is to take all the money they made from it and redistribute it as universal basic income, then make the models 100% free to use. Cat’s outta the bag, at this point I just wanna see the little guy get paid.
