I must have missed something - what do you mean?
Why is the existence of aiki-divebunnies and the brainwashed sensei who "throw" them remarkable anymore? Particularly by someone who doesn't do Aikido, but has been somewhat adjacent to it for many years?
Probably its just fluff. He needed to make a blog post on something, figured, "eh well I can bust on Aikido, haven't done that in awhile."
