Fake but accurate redux?

Heartland Institute leaked documents, and one that may be fake. [Link]

But in that press release, they unequivocally deny that the "Climate Strategy" memo came from them, or anyone in their employ.  And after reading through the documents, I'm inclined to believe them.  

Full disclosure: One of the donors in the apparently authenticated documents is Charles Koch, and my husband did a year-long fellowship with the Koch Foundation. However, nothing I'm going to write either defends or indicts Mr. Koch, who's actually pretty incidental to both Heartland's funding, and this story. 

I should also probably note that I disagree pretty strenuously with Heartland's position on global warming.  I not only believe that anthropogenic global warming is happening, but also support stiff carbon or source fuels taxes in order to combat it.  While I've expressed some dismay at the behavior revealed in the leaked Climategate memos, they haven't changed my mind about the reality, or the danger, of global warming.  I'm not defending Heartland's stance on climate science; I'm mostly interested in this because I have a longstanding fascination with fake quotes anddocuments

Now, caveats out of the way, here's why I think that memo is probably fake:

1.  All of the documents are high-quality PDFs generated from original electronic files . . . except for the "Climate Strategy" memo. (Hereinafter, "the memo").  That appears to have been printed out and scanned, though it may also have been faxed.

Either way, why?  After they wrote up their Top Secret Here's All the Bad Stuff We're Gonna Do This Year memo, did the author hand it to his secretary and say "Now scan this in for the Board"? Or did he fax it across the hall to his buddy? 

This seems a strange and ponderous way to go about it--especially since the other documents illustrate that the Heartland Institute has fully mastered the Print to PDF command.

It is, however, exactly what I would do if I were trying to make sure that the document had no potentially incriminating metadata in the pdf.

It doesn't pass the Ideological Turing Test.

5.  The worldview is different.  In my experience, climate skeptics see themselves as a beleaguered minority fighting for truth and justice against the powerful, and nearly monolithic, forces of the establishment.  They are David, to the climate scientists' Goliaths. This is basically what the authenticated documents sound like.

The memo, by contrast, uses more negative language about the efforts it's describing, while trying to sound like they think it's positive.  It's like the opposition political manifestos found in novels written by stolid ideologues; they can never quite bear (or lack the imagination) to let the villains have a good argument. Switch the names, and the memo could have been a page ripped out of State of Fear or Atlas Shrugged.

Basically, it reads like it was written from the secret villain lair in a Batman comic.  By an intern.
