The timing and the excuse they used is ridiculous. In the first days of Tyler's announcement, this thread was getting tons of messages, some of them had threats inside them, but back then nobody said anything about "out of control".
For me this is not a coincidence, they have finally decided about MKX on PC, but we can't know yet if they decided to continue or discontinue the game. In the first case, they may want to delete every negative comment regarding the issue before announcing something good. In the second case they will erase every trace the game ever existed on PC and servers closing might be on its way.
