Lightning does seem like the smarter mechanical design. Less to break on the phone side. Smaller overall. It's a shame it didn't become the general usb standard but I guess that's apple keeping it proprietary?
I'm not entirely sure why it happened… Maybe Apple thought that they could keep their own proprietary plug forever and that the EU was bluffing about forcing everyone to use USB-C? Or maybe they are happy like everyone to switch to a fragile connector type that will shorten the lifespan of iPhones.
I wonder what the EU will do when they eventually drop connectors entirely in favor of wireless charging.
