So the problem is that they are not blabbing their trade secret? And this is news? Coke has been doing that for a century.
I was more bothered by this blather about ethanol being "morally questionnable given the primary ethanol corn feedstock robs the food supply." From what I've seen, the genetically modified corn has been so scorned as "frankenfood" that the makers made it taste bad, to keep humans from eating it, and that GM corn is what is feeding the stills -- stuff we wouldn't be eating anyway. This has no more starved humanity than the growing cotton for fabrics. Check the production numbers, this is as false an argument as Obama saying "you can keep your insurance" while both the House and Senate bills say that in 5 or 10 years you can't.
