They also didn't buy that it reduced waste since they sell it separately.
Personally, it would reduce waste for me. I have a ton of those plugs and cables in many combinations.
But I could see how some people might not have it yet.
Perhaps Apple should have offered it for free for a couple years if you ask for it, rather than include it by default, and maybe they would have been better off here.
Edit: I'm wondering if I misread it. Is it a proprietary plug on the charger end of the cord? If so, that makes a little more sense, though there are generics for it for a while now anyhow.
