You're absolutely correct - these things can all be fixed. I think the main point is that it kills the excitement of getting a new expensive device. It just becomes more and more work to regain the control back.
Same with Precision Touchpad laptops (Dell XPS 15 for instance), changing all the swipe gestures to work exactly how I want. I always joke with my colleagues that if they can use my laptop efficiently, then I'm not done setting it up yet.
I totally get that it's a difference of expectations, it's just interesting to me.
