Since such data would not benefit buyers all that much (meaning new customers who have no choice but LC still wants to retain for whatever reason), and since Lending Club supposedly makes nothing on Folio fees, why should they add such things? I don't think LC has any reason to help you get your 92-95% (-8% to -5%), especially if that "savings" to you is essentially coming out of buyers' pockets. People who are liquidating are not desired customers. And they have shown time and time again that "traders" aren't desired customers either. They will not do anything to assist either of those two groups in my opinion.
No, I don't think at some point that data "HAS" to be more open to traders. Why does it "have" to be? They got by for the last 7 years just fine. What is suddenly different today? I don't want my trades published, and so far LC seems to see things the same way. Certainly they could change their minds in the future, but there would probably have to be some motivation. If it ain't broke, don't screw with it. And they've got enough stuff that truly is broken that they should be working on before even considering this Folio voyeurism.
