Surely this has been extensively double-checked and there is an explanation, but I'd be interested into what it is. I get the direction the likes of Uber and Lyft are coming from with the "we're just an app that connects 2 people", but the way Kickback is described on TC makes their "loophole" less obvious. I think they may be more geared towards one betting money against another that they can beat them personally, but it's not immediately clear.
