It's like the old phone jack that Apple wants to be rid of--a common and cheap standard that attaches to every known thing in the universe already. And replace it with what? A proprietary system that may be better in some ways, but reduces your choices. Now, I also use the Bogen hex pads--which means if I am out with my Nikon, or my Hasselblad, or my Fuji 6x9, or even my Wista VX, I am good to go.
Comparing the 1/4"-20 tripod mount to the 1/8" TRRS jack isn't a great comparison. The tripod mount has been a standard for decades and decades. The phone headphone jack fractured into competing standards years ago. Works fine for listening, but once you want to use a microphone you're dealing with different pinouts for different manufacturers, balkanized auto detection and signaling, incompatible plugs sizing, groun…
This is true, but ultimately they are all variations on the 1/4" phone plug, which has been a standard across multiple industries since the advent of the telephone. Adding another ring to a TRS, or changing the pinout, is a minor variation compared to Apple's alternative. The phone plug is so ubiquitous that I think the comparison is valid.
