It is amazing to me that Goldman Sachs didn't see this coming. They were selling a commodity product, had zero barriers to entry in their industry and were fundamentally in a business that Blizzard was prohibiting. They has huge risks of competition undercutting them (it happened), Blizzard breaking their backs (it happened) and even, if Blizzard would ever potentially permit this, why wouldn't it get into the business itself just selling the goodies from inventory?
