It's to prevent too many negative opinions from being posted. If Square Enix limits their board membership to subscribers they can much more easily control the board.
This way most of the members are die-hard fans who will all group together against naysayers and make their opinions seem lesser.
You're channeling Poubelle aren't you.
They limit who can post to people actually playing, if people can't see the sense in that I can't help you.
That being said, they should have a few
open forums, especially the General Discussion.
