I’d wager they don’t. The UI of apps is not the responsibility of the OS. It’s still not useless to be able to run desktop apps on a mobile device - while you’d probably struggle to use them on a 5" phone, most will be useable on a 12" tablet.
And - while annoying - you are able to zoom in on modern mobile OSes, so you don’t need a stylus to press tiny buttons.
