I'm not defending the system. It is quite evidently flawed. I'm objecting to the implication that the oil companies are complicit rather than victims of fraud.

It certainly seems to create an incentive to cut costs at the expense of quality. I don't understand why Green Diesel didn't just continue to produce poor quality fuel and thereby sell legitimate RINs.
