The rewrite, while simpler and arguably clearer, also seems more boring to me. It doesn't engage my imagination.
In any case, the original doesn't set off my "bullshit detectors". Such an aggressive way of commenting on a piece of writing! Not everyone must or should write like Hemingway -- not even Hemingway!
That's fair and maybe it is more boring. It was, after all, an off-the-cuff rewrite by some random person on HN. It wasn't written to demonstrate the ideal way to present the argument, but as a way of showing that the original used a whole lot of words to say not that much.
