Sorry - but Uber is very much a app first app. Most people using it are coming through the "proprietary" ecosystem parent wants to get rid of.
I don't use starbucks, but I wouldn't be surprised if it also had a proper app store app and didn't require users to use a web browser to access the app.
If anything - this proves the user preference for apps vs websites.
I like my apps to be apps and a lot of the "Apps" that are HTML/js are janky cross platform and are tricky to pay for (vs one touch on ioS)
