Yeah, that whole article needs to be re-worked really. Additionally, it was written by a player who was not writing it as objectively as I would like. Junkers are neutral in Gallia. Some of them have done work for the crown but just like anyplace else, they are primarily opportunists who prefer to stay out of the majority of conflict and quietly manipulate situations for their own profit.
I am much more comfortable with your clarification in the last paragraph. This seems more in the general behavioral patterns of junkers.
