> Why use Bluetooth at all if they don't actually use it properly?
Because they needed a way to get audio to the AirPods wirelessly and to work with their devices? That’s a pretty good reason to use Bluetooth.
I doubt they got together and tried to scheme a way to break Bluetooth in this one tiny little way for vendor lock in. You can use the basic AirPod features with other Bluetooth devices. It’s just these extended features that were never developed for other platforms.
HN comments lean heavily conspiratorial but I think the obvious explanation is that the devs built and tested it against iPhone and Mac targets and optimized for that. This minor discrepancy wasn’t worked around because it isn’t triggered on Apple platforms and it’s not a target for them.
It reminds me of the USB keyboard extender that came with old Macs. There’s a little notch in the socket so you can only use it with Apple keyboards. At the time I thought it was a petty way of preventing you from using it with any other device, but apparently the reason they didn’t want you to use it with other devices is because the cable didn’t comply with the USB spec.
Yes, USB extenders are not spec-legal (because the device isn't built expecting to be extended).
But you can have an extension cord which accepts USB on one end but doesn't accept USB on the other.
So the keyboard has a superset connector so that it can go in regular USB and notched USB, because it is verified to work right when using the extension cord.
This design also means you can't plug one extension cord into another to get an even longer distance (which the keyboard wouldn't expect). Pretty clever solution.
