I don't know what I need John Gruber is. But I'd say those quotes you pulled are pretty intentionally characterizing the potential (and legitimate) issues somehow acceptable. Why would I want Apple to regulate the third party headphones available to me? The headphone market might be a bit too large to track, but having that many choices isn't a problem in my mind. I'm free to research and select from the myriad options at any price point. Those who prefer to buy Apple endorsed products can go to their store and find Beats or whomever on the shelf. Tell me what advantage is gained by eliminating the other options in be market?
And I see no significant advantage to the change in technology itself. Optical ports provide a measurable advantage in sound fidelity over analog, but you haven't seen them eliminate composite or component ports from home receivers, because there are also significant disadvantages in cost and length of optical cables. I don't even follow that there's such gains to be made from switching to lightning...
Which leaves me at the obvious conclusion that this is just a ploy to sell more adapters and reap licensing fees from vendors at the expense of their customer.
And remarks he makes like "Cough up the extra $29 for a new pair" convey exactly the tone that is bothering us all.
