Note that the study was done on a Mac, by a Mac-user, so your point is partially moot.

drawing a big black rectangle is 10x faster and there is no way you can de-obfuscate that
Just make sure you're not saving in a file format that has a preview, where the preview doesn't have the obfuscation updated. :)

Once I hit "save" in photoshop and exit I can't undo. Although in a layered image the rasterized text (must be rasterized before we can liquify/blur it) would probably be on a separate layer, but it's generally much more incriminating to replace text and not unblur text and it's probably not layered like that.

You're not missing anything.
This guy tried to read some blurred text on his friend's site, so he decided to mess around in photoshop.
He got over zealous and did some javascript stuff in photoshop, based on blurring known text and attempting to reblur and match that text 1 letter at a time.
He was then disappointed that he couldn't use the thing to unblur assumed text of unknown font, font settings, color, language, character set, and blurring algorithm after unknown layers of image alteration after the text was rendered, and after unknown compression.

I don't think so:
known as the open-Apple key (as well as just "Apple") in documentation prior to the Apple Macintosh family of computers
However, you get pedantry points for trying.
