C is just a work around for B and the fact that the technology has no way to identify and overcome harmful biases in its data set and model. This kind of behind the scenes prompt engineering isn't even unique to diversifying image output, either. It's a necessity to creating a product that is usable by the general consumer, at least until the technology evolves enough that it can incorporate those lessons directly into the model.

And so my point is, there's a boatload of problems that stem from the fact that this is early technology and the solutions to those problems haven't been fully developed yet. But while we are rightfully not upset that the system doesn't understand that lettuce doesn't go on the bottom of a burger, we're for some reason wildly upset that it tries to give our fantasy quasi-historical figures darker skin.
