Quite. I'm not into MMO's, but from the outside it seems the clear path of subscription games is a short period of subscription, followed by F2P/P2W. I know there's a few notable exceptions like WoW and Eve, but isn't Eve now free limited access too?
I've never heard of a game going from a non-subscription model and then introducing one. Has this ever been done?
If not, and as to my knowledge FD has never suggested subscriptions, couldn't we stop raising it again and again?
Actually you can "buy" your monthly subscription with ingame currency in Eve.
And WoW introduced a new system where you can effectively buy playtime with ingame gold.
