That is literally the franchise, dude. That's what drew folks to it, that's why folks like it, that's what keeps them coming back.
The lore/story being a garbled mess that requires you to look up recordings of old concerts and a bunch of other stuff is just Squeenix being Squeenix and planning badly. It has nothing to do with any licensing, which only applies for the Disney license as Squeenix like, owns Final Fantasy and shit, yo.
