I also suspect that's one of two reasons that Apple hasn't shown an inclination to move to USB-C for devices that currently have Lightning ports -- the switch from the 30-pin dock connector to Lightning caused an awful lot of screaming. It's kind of a "damned if you do, damned if you don't" situation from a PR perspective: people are beating them up here on HN for pushing Lightning audio, but if they'd announced they were moving from Lightning to USB-C and dropping the analog headphone jack? They don't have that much Courage™.
The second reason is that the physical USB-C connector is thicker than the Lightning connector. Not by much, but it really is; in fact, it's about as thick as...a 3.5mm headphone jack. Right then. (This is also why the wildcard option of putting both a Lightning connector and a USB connector on the phone was a non-starter.)
I know there's an argument to be made that it's all about the Benjamins, that Apple just wants licensing money and maybe to wave around the DRM boogeyman. Maybe, but I honestly think that's more of a happy bonus for them than an overriding consideration. They're control freaks who don't like to share with others, but they're regularly on board with non-proprietary standards when they think that's what makes a better product. Remember, they were one of the first major companies out of the gate with a USB-C (only!) computer, and Apple was involved with the design of the USB-C connector.
I don't think that changes the point. The parent is saying that there's a difference between dropping a universal standard in favor of a closed standard.
There's a legacy connector in every box. All your legacy headphones still work. Apple didn't want to add an additional port and they can't exactly switch to usb-c at this point. In 3 years when all other phone makers drop the headphone jack for usb-c, can we get a lightning to usb-c?
And the parent is making a wrong assumption. Apple is not pushing lightning as the new audio standard. That's just a stopgap for people who insist or have the use case for wired headphones. The audio standard they're replacing it with is Bluetooth.
