that sounds like insider trading. price fixing would need not involve nonpublic information (beyond the actual conspiracy to fix the prices as it helps to keep that part secret normally)

I agree that "nonpublic" is barely related to the problem so how it's related to a solution is unclear. But it seems like this is the only general aspect of the outcome. Otherwise the outcome is just to stop doing this specific bad thing this specific time, and fines that are less than the profit made from bad behaviour.
