I read it.  
Here is a link that's not behind a paywall, if anyone else wants to read it.  You can type "44" in the page-jump at the top, or scroll down to "page 50" printed on the pages.  
I agree it's worth reading.  
That said, I divide this into 4 broad categories, as I so often do:  
1)  stuff I don't know about and so can't really respond to
2)  stuff I do know about, and the facts were wrong (I wish he'd have cited sources)
3)  stuff I know about, and the facts were right, but his thought-process was faulty, leading to bad conclusions or even self-contradictions
4)  stuff where the facts were right and I'm in agreement
I'm not making a percentage determination here, just noting that all four categories were present in the piece.  I won't dissect them here.....that was a long piece and to respond to everything would take forever.  
I will offer that I agreed with quite a bit of what he said.  Probably most of it.  Category 4 is likely the biggest.  Still, there's a couple of very fundamental, root-level ideas and beliefs he appears to hold which I think are demonstrably not true.  On some things he seems to hold an underlying, here-unaddressed philosophy that I think is missing some things in order to line up with reality.  
Still recommend if you have the time.
