Amazon was building expensive infrastructure and improving their brand, whereas people are increasingly coming to associate Uber as tarnished (don't pay their drivers enough, don't screen for rapists, dumpster fire politics, killed a pedestrian testing their self-driving cars recklessly, continue to hemorrhage money after a decade of operations).

Amazon breaking even is very different from Uber lighting cash on fire to keep the lights on. Amazon was working towards something - becoming the best online shopping place possible (and building the logistical infrastructure to make that happen, allowing them to offer better services such as guaranteed fast shipping). Uber is just continually rearranging the chairs hoping to keep it going as long as they can.

There is nothing about Uber that scales without losing more money. If there were, they would have figured out how to make money by now. It's not like they haven't had enough time and money.
