The reality is that the patent system exists, in all it's horrible innovation-stifling glory. It's business, nothing more. It's not right and it's ruining the world, but you have to work within the system until the system changes.
If there is other prior art, that's fine. So be it. But the author did not provide any of that art, and instead made false claims based on a knee-jerk reaction to something that he misread.
I don't like having to defend the patent system at all, but the author is in the wrong. Simple as that.
