> This is very weak a priori arguing. I could just as well argue that USB-C has the center blade shielded instead of exposed and so is more durable. The unshielded Lightning center blade is on a $5 connector. If it breaks, I'm out $5 and it's reasonable to have spares. The shielded USB-C center blade is part of an expensive device. If it breaks....
Have you ever seen either kind of port break on the inside? This speculation is just as weak without any evidence.
And for what it's worth, damage to the center blade does seem to be a common failure mode for USB-C and mini-usb connectors. Less frequent for something like HDMI but it does seem to happen from time to time. Lightning never felt like it locked in as securely as USB connectors do, but at the same time, every time I saw a damaged lightning connector it was always on the male (and therefore usually cheaper accessory) side.
