Proving what point? Apple knows its userbase will take it up the arse and like whatever they make/change.
They removed the headphone jack not for water resistance or other excuse. It was purely for future profit potential in selling first party AirPods & Beats with exclusive features that 3rd party bluetooth headphones cannot use.
They forced the change. Had they kept the headphone jack and kept including 3.5mm earbuds in the phone, the AirPods would not have been as successful.
