What are you talking about? The MicroUSB connector everyone is familiar with only has 5 pins.
You are confused, and you're wrong about this. And you even posted misinformation on that blog writer's site.
The microUSB adapter that just about all other phones use, including the revered Galaxy SIII looks like this:
That's the adapter that everybody is whining about the iPhone 5 not using. But that is a 5 pin adapter. Here's the pinout:
5 pins. Apple lost functionality going down to 8 pins, which was stupid in my opinion. But they still needed more than 5 pins. That's what the author is saying.
USB 3 micro does not have 11 pins. What you're likely thinking of is the 10 pin USB 3 Micro B. Which looks like this:
That's your 10(11ish?) pin connector. But how many devies currently use that? That's what you're arguing with, but that's not what other devices currently use.
And you are also wrong about the amperage part too. MicroUSB like the beloved format everybody wanted, can only transmit 900mA of current.

A unit load is defined as 100 mA in USB 2.0, and 150 mA in USB 3.0. A device may draw a maximum of 5 unit loads (500 mA) from a port in USB 2.0; 6 (900 mA) in USB 3.0. There are two types of devices: low-power and high-power. A low-power device draws at most 1 unit load, with minimum operating voltage of 4.4 V in USB 2.0, and 4 V in USB 3.0.

The iPad requires 2A of current. MicroUSB does not and cannot provide that, as pointed out above. For reference, the Galaxy SIII requires 700mA.
That blog writer made some stupid errors in writing, which has been pointed out, and the author corrected them. But he does have a point about most of that. You should post an apology on that poor guy's site for hammering on him.
