You're right that they should stop trying to copy Apple, and instead try to make something better. To me, Android is only more open and flexible, but it's not better. It might be good enough, though, just like Windows was good enough and more "open" than MacOS.
But without the right product, no amount of marketing is going to get you any real volume. And without volume, no amount of supply-side management is going to get the great product margins.
