A gorgeous otherwise-monochrome painting that happens to use a little bit of mauve isn't a worse painting because of the mauve. If that painting is nominated for inclusion to a contest that requires the use of only one color, it is correct to reject that painting from consideration. This rejection would only be a problem if the requirement wasn't clearly disclosed up-front.

As for the rest of your commentary; you're free to gather likeminded buddies and start the "Robot-Generated-Art-Inclusive Indie Awards". As a bonus, I expect the fuckoff-huge studios would be quite excited to quietly help fund the project through cutouts.
