I always considered the articles posted on the webite with their links distributed on the forums from “Steve” were merely ghostwritten. The link to the Internet Archive I provided above indicates that at least some were most likely originally written by Steve and later reworked. The fact that they have been reworked multiple times with the style becoming more edited (eg. with videos embedded, restyling, etc.) gives the impression that they were at the very least edited by someone else, not Steve himself, especially considering Steve no longer works at LingQ. I suspect the marketer has taken some “professional licence” to rework Steve’s article here to better achieve the goal of sales.
Steve’s YouTube videos are clearly him though. I watch his videos but don’t bother reading the LingQ marketing material on the website.
