I'm not sure I understand the point you're making. Its disheartening that artists can opt-out of having a computer algorithm make derivative versions of their creations?
I'm probably on the opposite side of the fence. I do find it disheartening that it's opt-out instead of opt-in. The training set should be limited to public domain and CC-0 until such a time it can comply with attribution; then other CC works could be incorporated.
