Based on what? I'm pretty loyal to Uber and use it because I know what I'm going to pay when I order the ride and because I'm not pressured to tip in the app. I guess if another app had both those features, the same ride availability, and cost the same I'd download and try it but currently none of them, that I've tried, do.
The naked capitalism series is written by a cab dispatch consultant, and reads almost like a paid hatchet job. Makes huge assumptions on data not in hand, and spins iffy conclusions with evident bias. At one point he claims Ubers costs can never be as low as cab dispatch because Uber is spending money expanding! That makes zero sense.
It's pretty clear Uber is in heavy investment mode, in market expansion as well as new businesses (uber-eats, self driving cars, etc), no one can know what their real costs per ride are unless they can break out that detail.
But it's also clear in their core business their cost to dispatch a ride should only be pennies.
