My guess on what the author means by aspiration porn is Apple sell you a product by selling you aspirations: you can be more healthy if you have an Apple Watch, you can be more connected if you have an iPhone, you can be a great developer if you sell on the AppStore, etc, etc.

More generally, I think people's complaints about Apple are due to a combination of brand engineering and market dominance. Apple make amazing hardware, they market their products as premium and they price it accordingly. If they made inferior products, say Surface Books, nobody would care about it. If they didn't sell at high price, they wouldn't make big money which will limit their ability to innovate (or polish if you will).
