I disagree with some other comments. I think it is totally possible that Apple removes Uber from their Store. That&#x27;s the danger of all the &quot;closed&quot; and &quot;restricted&quot; app stores.<p>1- Uber has a web app that works on all platforms that can run a modern browser (pretty much all in fact). Right after the app is taken down, they would publicly push all iPhone users to use the web app.<p>2- People would buy other devices where it run natively (Android, smartwatches, etc.).<p>3- I bet Uber is already working on a plan B to mitigate that. Like building their own device, integrating with car manufacturers, etc. They could be even working on creating an alternative mobile OS. 
Having Uber natively integrated in a mobile OS could be a huge opportunity to grow with other features and become the next generation iPhone. It would also be a differentiator to the iPhone.<p>The mapping API they use could also be taken down or blocked. Same risks there and that&#x27;s why they are working on their own mapping technology. They tried to buy HERE maps but it failed.
