This is apt.
By making excuses for Square-Enix (or any company) to add more content outside of the sub, you're actively devaluing how much your subcost is. You're saying, "My 15 (or 12) dollars isn't enough. You deserve more money." To the far extreme, this develops MMOs like Star Wars the Old Republic, where all of the good looking armors are in gambling boxes purchased with real money -- including armors that existed before the gambling boxes did, which were taken out of the game so that you can only get them by gambling.
