There are a couple of things which stood out for me in this video.
One is that the analysis implies that a cable can be evaluated by cutting it open and looking at it’s parts. (DeCooney raises a question as to whether even that is done accurately.)
Is a cable just the parts inside? Is that all there is to cable design? That’s strongly implied in this "Wizard of Oz Reveal" approach. A lot in audio would suffer by this approach. But that’s not really fair to the work which goes into testing, materials science, and design -- for most audio. Are cables a special case of "what you see is what you get"? If not, then this video is seriously deficient and perhaps deserves the label, "disinformation."
Also interesting (to me) is how typical this kind of video has become -- not just for OCD guy but generally. It’s the "myth-buster" trope which deploys the lingo and rhetoric of techno-scientific analysis but which doesn’t follow through with sufficient evidence and argumentation. Of course, providing those would make the video too long for those simple-minded viewers who want to click on another video, ASAP. Those viewers just want their biases confirmed and their jolt of outrage for the day. That’s understood by the makers of this video. Bread and circuses for the plebs? You got it. Say what you want about ASR or Audioholics, they do not engage in this.
Ultimately, this approach is, in my opinion, destructive. It is a way of solidifying know-nothing tribalism. It elevates the maker as a "trusted authority" who lets you in on a little secret that the "powerful" and the shysters don’t want you to know. (Then, he says "Come, buy from me. Your trusted authority.") But it doesn’t teach people how to think and evaluate these issues for themselves.
