They realized the truth. People may complain a LOT about things not being their way.. but.. enough will stick around and slide the card for any pixel they push that it doesn't matter. Enough of those that left now will be back in 9.1 so they can soak a month or two of subs, maybe a couple gold coins, hell a few of them might fall for the 6 month sub thing because they attached a mount and simple repeat.
WE THE CUSTOMER base more or less created this situation. Some people really like it and if they buy it that way then that is fine. Some people really hate it and bounce. But a LOT of people just sit around and bitch and moan while paying for the product. Those are the ones that enable the whole situation to remain in this limbo.
