No, Apple, killing your headphone jack is not 'courage'

I've been at or watched every Apple keynote and product launch event since 1998. I was there when they killed the CD drive in the Macbook Air and the 30-pin connector in the iPhone 5. I've witnessed the demise of every Macbook charger. 
And I've never heard anything as ridiculous emanate from that stage as I did Wednesday, when marketing chief Phil Schiller explained why the iPhone 7 would not have a standard 3.5mm aux cable input, better known as the headphone jack.
