At what point do drivers tap out? This match keeps cutting their hopes dimmer and dimmer.
This attitudinal difference is most acute when the driver drives for both: they generally like Lyft better for how the company treats them but are also on Uber to ensure steadier business.
At least, this is the argument that Uber/Lyft will/does make to shield them from general liability for their contractors' actions as well as tax liability[1].
