Travis is right on a technicality they did not lower Uber Black prices much if any. What they did instead was coerced Uber Black drivers to take Uber X request. Yes drivers can reject Uber X request, but if you reject a certain amount of Uber rides, they kick you off their system. Probably why the driver is complaining about going bankrupt, you need a luxury car to drive Uber Black, but if you're stuck picking Uber X…
I believe it simply sets you to inactive temporarily, because you're obviously not picking up rides and you're slowing down the rider matching process.
