The more charitable explanation is that the pins for the lightning connectors really do not wear out. This complaint is a made-up problem and in the real world it does not actually happen any more than someone accidentally jamming something into the usb-c port and breaking the center connector. Lighting ports do have one problem usb-c lacks: they collect a bit of pocket lint that can impact connections and eventually needs to be scraped out using the sim ejector tool (or a paperclip.)
True about lint in lightning ports, but not entirely true it doesn’t happen in USBC. Probably less common, but I know somebody who had to get some saw dust out of a usb-c port.
