I do not recall any example of Apple overtly listening to customers unless pressed by class action. That's the irony of this feedback post. Apple is just not an org that takes direct customer feedback (like you've noticed from their "you're holding it wrong" debacle).

Also, they've probably done the maths and knowing their "loyal" customer base people would be more than happy to pay for multiple redundant devices just to have them seamlessly work together. They are in business of selling premium devices to people who have low sensitivity to price and cost
