Earlier quoted context omitted.
Well the rest of the phone manufacturers settled on mini usb followed by micro usb. Prior to that there were a ton of proprietary phone charger/data cables, so it did help some
The EU luckily didn't put their foot down so phones were allowed to progress from mini-usb over micro-usb to USB-C. It definitely helped a lot (but Apple still kinda ruined it).
Not quite sure what to think of USB-C yet. Certainly feels more mechanically solid than micro-USB, but subjectively, the plug connection seems a bit slippery. Cables seem to disconnect spontaneously more than they do with e.f. Lightning.
