Protecting me from using my existing cables? Gee, thanks.
> using my existing cables This won't apply retroactively, new iphones after X date will have to be shipped with USB-C
No, but the parent’s point is still valid - many people own more than one lightning cable and/or lightning-enabled accessory (charging docks, stereos, etc) and as soon as you own an iPhone with USB-C, they’ll immediately become either useless or require yet another adapter.
This already happened once when the iPhone switched from the iPod connector to Lightning, and people revolted for this exact reason.
