Not sure why you're downvoted. Apple led the charge on a fully usb-c ecosystem. There are billions of lightening devices out there, so Apple has been transitioning over multiple years. The charger side went usb-c awhile back. Now most users should have usb-c chargers, and likely a few usb-c cables. When the iPhone changes this year or next, it won't be a big deal. People forget when Apple went from the 30-pin to lightening there were a lot of complaints. This though, Apple can point to the EU and say 'they made us', even though they have been headed this way all along.
