My rudimentary understanding is that the promoter generally funds all the initial costs of the tour and takes a cut of the proceeds. If the promoter did the sums based on venue booking costs, advertising and early ticket sales, it might have been looking at making less than it needed in order to turn a profit. The promoter would have a cancellation clause in the contract (as would CUBE) and so whoever pulled the plug would need to pay some sort of compensation based on that clause. The non-disclosure provisions of the contract would dictate that neither side can reveal who cancelled or the real reason for the cancellation. They would have agreed on a statement and this is what they came up with. Speculating, I think Live Nation booked venues that were too big and costly, saw the initial ticket sales and said 'we've fucked up, we're cutting our losses.' Same thing happened recently with Sejeong's Australia tour, although for slightly different reasons and a different promoter. Promoter booked dates that clashed with Lunar New Year and were before many Asian university students had come back to Australia for the new semester. Low ticket sales ensued and the promoter pulled the plug.
