RIAA Spent $64 Million On Threats Netting Just $1.4 Million

All that observation does is move the question slightly, from "Did the ROI on the litigation make sense?" to "Did the cost of the litigation scare off $64 million worth of file sharing?"

It's pretty clear that the ROI on their litigation did NOT make sense. It also seems unlikely to me that they got $64 million worth of "scare" from the litigation either. But I'm not an RIAA member.
