I spoke to a Lyft/Uber driver today in NCY. He said that Uber's losing drivers every day here — about 5% (I don't know where he got those numbers from). He also mentioned that Uber are flat out lying about how much drivers earn, and in some months drivers that aren't on Uber's "favourites" list end up owing Uber for renting the gear instead of earning money.

This reputation is definitely damaging, and it's common knowledge here. Drivers bitch about it. They recommend Lyft.
