I hope that they don’t think that this is going to work just because their decision to scrap the headphone jack didn’t go insanely bad for them. Bluetooth earphones were and are just as good as traditional ones...plus you could always get a cheap converter (dongle).
With cable vs wireless charging, cable is faster, more versatile and arguably as convenient (try wireless charging in a car or anywhere other than on a still flat surface). Wireless charging is still quite slow...plus there is no converter.
As for potential revenue to make from it...wireless chargers (especially the good ones) are already made by everybody. Heck, I don’t think Apple even makes a wireless charger ever since AirPower was cancelled.
