For sure, a lot of the value proposition of Uber could be seamlessly be replaced by a different company. However one thing that Uber has that is totally proprietary to them is their global mindshare. For example, when I go to the US, I use the Uber app whenever I can, because it's the exact same experience as at home and I know what I'm going to get. For travellers, this continuity of experience is great.
Maybe so, but I didn't even bother using Uber in a country where all the guides recommended another app because it's more popular. Consumers aren't enterprise, they'll switch faster if they think they'll get a better deal.
