Uber has the same problem that Death Stranding and Resident Evil have: you can't keep shittons of data cached on-device unless you have it installed as an app and not a webpage. Uber specifically needs to support someone traveling from Sao Paulo, Brazil to Mumbai, India without needing to have more than a whisper of connectivity at their destination. The way you do that is by keeping the UI for every payment provider in the world in the app.

F2P mobile games need to be able to send you notification spam, because they're based around habituation and addiction. You couldn't do that in MobileSafari until very recently[0].
