I consider most of the BW fodder to mostly folklore, but don't doubt there was a time and place during the transition from the industrial age to the technology age where a bettor held an edge. Personally think that no longer exists.
As for Mr. Malinsky, there isn't any flies on that guy; that's for sure. Astute professional in all aspects, and has my admiration. The author of this article is no journalist, and relies on embellished fiction foregoing documented facts. Legends grow, that I know, but often not reality.
Poorly written sensationalism, but adequate toilet literature suitable for the likes of the national inquirier.
My opine, of course.
