They've recruited a lot of the NYC Uber drivers. They've been paying them $25/week to keep the Juno app open while they're on duty, collecting information about driving habits, routes, etc. The drivers' relationships with Juno won't be as contractors, so Juno will have much more control over the drivers - such as having exclusivity agreements.
The idea seemed to be to bring on all the drivers as employees, destroy the population of (good) Uber drivers, and advertise the app. The plan is that everyone in NYC switches to Juno, since you won't be able to get an Uber in a timely way, and Uber's quality will be bad because it'll just be the "leftovers" of the driver talent pool.
That's what I remember getting out of the conversation, anyway.
