I saw a 3000-word rejection letter

Context
Someone on Help a Reporter Out made reference to a 3000-word rejection letter that was on the internet as an example of something job recruiters shouldn't do. When I sought out the actual contents of this letter, I found them on Gawker, which also included comments from the recipient who forwarded the letter, and two catchy titles.  

Commentary
OK, it's official. All of my inspiration comes from HARO now. Plus all that, I deliberately titled today's entry as search engine bait, because "3000 word rejection letter" has become an internet meme. I have lost all my morals.

Anyway, I was surprised at the amount of vitriol thrown at this this list of dos and don'ts from Shea Gunther. In particular, I don't understand the accusations of arrogance and condescension. Both of those terms imply to me, "This guy thinks he's better than his applicants." Perhaps I have too hierarchical a view of the world, but to me, the person who not only has a job but has a job to offer is, in fact, better than the applicants. At least in the job-hunting realm, which is where rejection letters come from. Moreover, I think we can all agree that Mr. Gunther is better at seeking employment than the people whom he apparently encountered who applied for a writing job without proofreading for spelling and punctuation!

I'd like to believe I would not have been offended if I had received this letter. After all, it's obvious from the first paragraph that it was sent to over 900 people. Which means that each of the criticisms contained in it belong to one of three categories:

1) Doesn't apply to me. Water off my back.

2) Might or does apply to me, but not something I want to change. Great, now I know I would not be a good fit at Shea Gunther's place of business.

 3) Might or does apply to me, and I didn't know it was a problem. Yippee, something I can fix before my next round of job applications.

So where's the down side to any of these three scenarios?

 Is it just considered rude to say, "Some of you are really bad at applying for jobs."? That can't be right, because career advice websites do it all the time. So then it looks like we're mad at Gunther because he actually has some interest in receiving good applications, as opposed to people who are spouting the same old cliches in order to create column inches.

Here's a scale of types of rejection letter I'd like to receive. OK, I don't like to receive any, but you know what I mean. From least-favorite to favorite:

1) Dead silence. Hello, is anybody there? Did you get my application? Does your company still exist?

2) Polite, meaningless form letter. By far the most common of rejections, it gives me no help whatsoever, except to know for sure I didn't get the job.

3) Something like what Shea Gunther wrote. It's like an extra 3000 words of job ad I can build on for the next time!

 4) A personalized rejection saying exactly why I didn't get the job. This would be golden, but according to most human resource offices, also actionable. Isn't that great? Someone takes the time to tell me why it wasn't a good fit, and I sue them!

What did you see today?
