Facebook's mobile app is utterly massive and it still runs mostly okay even on weak devices.
I agree with your comments but this is a bad example. The Facebook app is horrible to use on high end devices. The mobile website is much more performant and has most of the core functionality.
The app is actually worse in one way - they chose to use the iOS WebView that doesn’t support the native ad blocking framework. So when you click on an external page, it’s usually horrible - bacause modern web.
