This is exactly why the hardware + software vertical integration philosophy is fundamentally retarded. What it essentially means for N hardware vendors to each have their own software platform is that as an application developer, instead of having to develop ONE application, you have to develop N applications. Imagine if Apple hardware just used Linux and macOS / iOS / whateverthefuckOS was just a desktop environment project like Plasma / GNOME / COSMIC. You could still keep the exact same particularities / UX flows / ease of use that people expect from Apple products, AND get free access to the wealth of software and content which exists for Linux and ALSO Windows (because of wine).
