Their return policy is designed to make you buy things without thinking too hard about it or worrying about the quality - the "ah who cares, if it sucks I can just return it" mentality. That strategy means that you buy things you don't need, causing a TON of environmental externalities. So, yeah, they'd have more fraud - maybe their return policy isn't compatible with the environment. Maybe their profit margins are not compatible with the environment. Maybe... just maybe... their entire business model isn't compatible.
