We have gone from one standard interface, to now three interfaces (headphone jack, USB-C and lightning), and one of them is proprietary.

We move from a world where you can buy any set of headphones, and use them with any device, to a world where... nothing is compatible with anything else. Either you use a permanently connected dongle, or you buy multiple sets of headphones.

The future is stupid and I don't want to live in it.
