I did not overlook the devaluation of the product in the title, which can only be a result: "Snake Oil". This is why I said: "No measurements AND no experience." But he came to a conclusion: It's snake-oil. Unprofessional.

I'm pretty sure you don't honestly believe that even the most outlandish claims from the least credible sources deserve rigorous testing before they can be dismissed. The only people who aren't willing to draw a line somewhere and conclude from the manufacturer's lack of convincing explanations for their implausible claims that it really is bullshit, are people engaged in the same kind of scamming and trolling.

No honest, reasonable assessment of this "product" and its marketing can conclude that the manufacturer appears to be on the level. Expecting journalists to wade through literally infinite bullshit from people not acting in good faith before reaching a conclusion is absurd. Your perverted idea of what journalism should be is far more harmful than any journalistic laziness that may be on display here.

To be fair though, audiophile reviews never contain any actual measured data either.

That's not fair at all! At least not to the major audiophile magazines, here in Germany, or such a prestigious publication like "The Stereophile". Just two examples:
