I don't think any of the people mentioned are "hand tools only" woodworkers, and if there are one or two who are, so what? They are in fact people who have videos or books showing or teaching hand tool techniques and hand tool use. Or offer courses, online or in person. Which is all perfectly fine.
Given that anyone can post videos on Youtube and create their own website, being "notable" seems to be literally anyone with an online presence.
