What's strange about this story to me is what exactly Pepsi would do with this information. Clearly, the recipes for Coke are hugely valuable to Coke and, if released, would allow another producer to replicate Coke and sell it. But would Pepsi want to do that? Would they release a new version of Pepsi that tastes just like Coke? Release the secret formula into the public domain? Of course, since Pepsi voluntarily contacted Coke and the FBI, they didn't want these secrets, but hypothetically what would they do with it?
This just wouldn't seem to help them. If "Coke" entered the public domain and anyone could produce it, then presumably many would and Coke would be forced to reduce their prices, which would likely force Pepsi to do the same or risk losing lots and lots of sales. [But your supermarket brand cola would probably taste a lot better...] Pepsi is being played off as acting ethically here, which I guess they are, but it's more a matter of Pepsi following its profit motive to maintatin the very profitably duopoly that they have with Coke than any corporate desire for "fairness" or something like that.
