I did wind up replacing the USB C ports on a 4 year old computer recently because it was dodgy as hell. When i got it under the microscope it the longer bus power pin contacts (and one or two of the others) had been badly worn/squished/stretched in a way that I guess was causing them to bridge to other pins. I assume some USB-C cable had some gunk in the connector which was hard enough to damage the contacts on the center blade, and the user didn't notice (because how often do you look into the end of your USB-C cable?). It probably presented as a cable that wasn't seating right or didn't go all the way in and whatever was inside probably fell out when it was removed and they tried again.

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.

I've had multiple USB-C chargers broken like this.

Now, admittedly, "being yanked by a robot vacuum and falling on the ground" is outside the design parameters for a port; but I absolutely had USB-C ports fail in a way that Lightning would have not.

(Not the person you're replying to, but also a "Lightning was a better physical connector than USB-C" weirdo.)

I have seen multiple USB-C ports break on Lenovo and HP laptops. About 1 in every 50 laptops over the span of 2-3 years. I don't know if it was the users fault or a manufacturing issue. But the manufacturers fixed these under the extended warranty.

It might be an issue with the USB-C port used in these laptops since the ports on MacBooks feel less wobbly to me. But in the end this is just speculation and anecdotal.
