This article doesn't mention two of IMO the most interesting properties of Lightning.

The first is that Lightning isn't simply a proprietarily shaped USB connection. Instead, it's a system where the pins can be re-assigned to different communication protocols. For example, one might make a lightning-to-RGB-video cable. This wouldn't be like a dongle or a conversion cable, where a USB device is talking to an interface board (like the old style USB-to-serial or USB-to-PS/2 connectors of the nineties); rather, it would allow an iOS device to send a native RGB video signal down the cable.

This move has its roots in how the old Apple Dock Connector could transmit raw video and audio signals, on top of the USB and other pinouts that were in that beefy plug. I've never seen any Lightning cables that did anything other than a USB signal in the wild, though.

The other thing is regarding the design of the lightning connector. There's a little tab on the plug; that's the weak point in the connection, if it ever breaks, it's almost certainly going to be due to the tab breaking. It's not a big deal, though; the tab breaks, you just get a new lightning cable.

Now most folks might not realize this, but USB-C has a little tab too; except that for USB-C, that tab is on the device. Look inside the port on your Macbook or iPad, you can see that little guy in there; the USB-C plug is actually a sleeve that fits over the tab. 

The thing is, that tab is still the weak point in the connection; but now, when the tab breaks off, it's your Macbook or iPad that is damaged, and more likely than not it's a non-repairable part. (not the case with Mac Studio, actually, but I digress). Say what you will about industry compatibility or proprietary parts, but on a purely technical level, Lightning is a far better designed connector than USB-C.

In an ideal world, Apple would have given away the license to the Lightning connector to the USB Consortium and said "hey, this should be your design for USB-C, have it, it's yours." USB-C would be a better plug, and Apple wouldn't be in this position of having to change ports and make an entire ecosystem of accessories obsolete. c'est la vie
