The Scions of the Seventh Dawn make ample use of it in the defense of Eorzea. The Sons of Saint Coinach actively teach the art of summoning to others, rather than hoarding that knowledge, taking it home, and reviving it there. Even the Students of Baldesion seemed to be more in that camp, being a group to freely support the scions.
I think a compelling narrative could've been the defection of the Red Mage Order from Sharlayan as a gesture of revolt against the archaic and often damning isolationist policy. Such a thing would've paved the way for some interesting internal conflict in the nation that would've led brilliantly towards an expansion in which we go to Old Sharlayan as well. Heck, the cinematic for that expansion would've probably featured Derplander as a Red Mage, similar to how they've been a Dragoon for Heavenwards, and a Monk for Stormblood.
Instead, we're seeing Red Mage as some kind of hidden society that has existed since the Flood, doing... something? Red Magic isn't even known about by most Eorzeans (or really, any), nor has there been any mention or hint of it from Sharlayans (outside of various speculation linking it to Sharlayan, falsely). It hardly seems that Red Mages are really the opposite side of the coin here, if anything, they'd have to be more isolationist and against sharing their magic than Sharlayan has been in order to remain hidden for so long.
