The oil traders could move to WhatsApp or somesuch but I'd be kind of sad if they went. The other day I was trying to get free historical stock data via an API and Yahoo Finance was about the only thing that did it ok.

Yahoo could assure their financial future by going massively long oil futures and then putting out false messages about Saudi Arabia having been nuked by ISIS or some such. A tad illegal perhaps but an offshoot in some ill policed part of the world could do it.
