This destroys a lot of value. Most taxi companies suck for reasons independent of their tech stack. (The fact that they’re better post-Uber shouldn’t obscure the effect of that competitive pressure.) Moreover, having a transport app that works in most countries is a value add for such a service’s most-profitable customers. Finally, the claim that taxi companies treat their drivers better than Uber applies in some markets, but it doesn’t in most, e.g. New York and New Delhi.
Uber isn’t profitable as a company, but they’re profitable in some (and a growing number of) markets. There is a recurring set of Uber hot takes that get recycled every few months that ignores this.
