It looks more like EBay and less like Uber. The more you exercise control over prices, quality, and service, the more you offer a service instead of just being a middleman.
I take Uber several times a week. I think of it as the service. E.g. when the driver takes a shitty route, it's never been the driver's fault. They're just blindly follow the company-provided navigation. So I never leave a less than five star review and whenever I file a request for rate adjustment (maybe once a month), I take care to point out I'm blaming the app, not the driver.
