Here is what developers want:

    Platform independence 
    Choice of tools/language
    Control of customer data
    Hardware independence

Here is what corporate platform owners (Google, Apple, Microsoft, Amazon etc) want:

    Platform lockin
    Minimal support costs (one language, one SDK)
    Control of customer data
    Control of the ecosystem
    Hardware independence
    A vig on every transaction 
    

There are very few intersections between the interests of developers and the interests of platform owners (be that Apple with iOS or MacOS, Google with Android, or MS with Windows). This is why the web will win IMO, it's one of the few platforms focussed on what customers and developers want, and not owned by a single corporation (though Google has come close).
