This is really interesting, because this changed. I noticed the default free CDN option was JS when version 5 of FA came out, but now the default is font based: https://fontawesome.com/get-started https://fontawesome.com/get-started Note the tab order, it's Font | Js | Desktop | Advanced. It used to start with JS, so I think you may be wrong on this point, even if they "recommend" it in their docs, their defaults argue otherwise.
