In fairness, Chris Odom also says it mitigates risk but does not remove it. Much like DPOS has a managed decentralization, Open Transaction isn't full on decentralized either. It really isn't that much of a competitor to Bitshares. I do not understand it that well, but it might very well be something to be used by bitshares at a future point.
They just need voting pools on top of ethereum. Yea thats the ticket !
