Here's the way I see it, they're losing tons of money off these things, they lose money having to pay for the servers which get no business. Also, if you think about it, someone starts graal for the first time (on trial), he then randomly selects a poor quality playerworld and his disapointed by it, where as if he chose a more high quality playerworld, he may have bought an account.
It's just a thought, anyway.
