I knew exactly what I was getting when I purchased all of the iPhones I’ve owned over the years and the cable it came with was more than sufficient. If I needed a different cable, I bought it. If I needed to use an adapter or a dock, I used it.
With that being said, if Apple continues with the lightning port, fine and if they change it to USB-C then that too is fine. Not having a USB-C port on my iPhone is not impeding my usage whatsoever and “I believe” it’s not impeding the usage of many other iPhone users.
