That's kind of part of the point. It's a form of encouraging people to buy their other games and play them.
While a lot of this post was really harsh IMO, I agree that Matsuno relies a lot on exposition dump and "tell, not show". And frankly I think that's bad writing.
The worst aspect of XII, for instance, is that everything remotely interesting after the escape from Rabanastre happens off-screen and is only told to us rather than shown.
