When we're talking about saving money on hardware it's not just the cents on a part that matter - manufacturing time and complexity (do we need a robot for the button? a hole drilled? will it fail? does it has to be repairable? do we need an additional employee on a manufacturing line to install those buttons?) is a bigger weight than just the part itself.

And companies will absolutely build a crappier product for you to save on manufacturing time. You're talking about a company that led the field by removing a headphone jack to make their manufacturing easier.
