That isn't to say they don't, it's just a cultural attitude inside the company. It's a crying shame because their content teams have obviously great taste and are willing to experiment, and they must be pulling their hair out over this, but yeah – AAPL should not only do more and better marketing, but consider licensing their content out in a limited fashion to draw people in, especially if they're going to maintain 'the product markets itself' – I can still buy iPods in BEst Buy, for an example.
People WANT apple to succeed on this content front. The Apple Vision program especially would benefit from high quality content, well-marketed, especially to drive adoption and thus reduce cost; amazing immersive/interactive content is the killer app for AR/VR if you ask me.
Let silly Zuck make dumb avatars and fake lowbrow games, if I'm going to project content directly onto my eyeballs, let it be Oscar-worthy.
