I never understood this complaint. AFAIK, I've never seen a macbook with a lightning port or the older 13-pin iphone port. If someone had an iphone, they had a USB-A to lighnting cable. Now they need a USB-C to lightning cable. Then you can use the macbook to charge your phone, or the usb-c charger that charges your laptop to charge your phone. Or yes, you can get a usb-c to usb-a dongle - but you can just as easily get the appropriate cable. I'm also seeing that Apple is going to start producing usb-c chargers for iphones and ipads (with a usb-c to lightning cable) in the near future.
I'm a macbook + android user, so I've had USB-C phones for a while, so now I can use the same cable and charger for my laptop or my phone.
