This might’ve been said but I felt that was the point. Characters like Jolee, Qui-Gon, and Luke could be considered “grey” relative to the status quo of the more fundamentalist Jedi, but that philosophy is more in line with what the Jedi originally were, before they became more dogmatic. So Qui-Gon and Luke are what the Jedi are meant to be, so they shouldn’t be called “grey”. They’re just Jedi. If anything, the prequel Jedi could be called something different.

Also, the “I can use both dark side AND light side powers!” idea that people equate to grey Jedi is different from new Jedi like Luke who acknowledge their inner shadow that everyone has rather than ignore it, like the Prequel Jedi did.
