When a company like Uber takes a cut from the driver, a part of that money is used to pay for the people that work for the app, but there are a lot of non-technical useful roles that keep the wheels turning: support functions like customer support / incidents / legal and onboarding teams make sure that the drivers and clients are safe and that they are not breaking any laws.

Liability is a second thing. Cost is one of the factors that might make people swing to other apps, but you also want an experience that is legal and safe, and at Uber's scale it takes quite a lot of people to synchronise this, as the liability for things like that belong to Uber and not the driver.
