I wonder whether they've considered the possibility of open-sourcing their apps and backend. Perhaps this is just Pollyannaism, but I tend to believe that workers' rights and open-source are the perfect match in a market like ridesharing. "Just goodenough" open source solutions have difficulty breaking through in consumer software (e.g. the mythical "year of the linux desktop"), but in a market like ridesharing, worker coordination could easily provide the push to critical mass.
