I find this completely unethical. You're basically exploiting every single artist whose art was used - without agreement - as training data for Dall-E.
It would be different if all the training data was art that was explicitly licensed for this.

Would watching a lot of animated movies in order to learn how to create good animated movies yourself be unethical as well?
Human brains also use anything the human can see, feel, hear for training. And what you produce in terms of creative outcome is a result of your experiences. But you don't owe anyone anything for training your human brain -- even if you use your brain to sell paintings, music etc.
And I stand by my point, it should be artists who decide whether their work should be used as training data for networks that get commercialized. If your work is used as training data, it is essentially an integral part of a product that is being sold without consent. Does this sound ethical?
