I think they clearly threatened the RF that they'd spill everything if they didn't get what they wanted, and were confident this was a winning hand.
The RF did what everyone should do when being blackmailed: they didn't give in to threats.
The result was Oprah, Netflix and Spare all a great big 'we told you we'd do this.'
The thing is once you've played your hand, and your opponent has taken the blows, then what? You have nothing else and you haven't won anything, you've only lost, because you didn't get what you wanted and your power has gone, you used it.
They went all in and lost.
They really thought they were going to cleverly play the fuddy duddy royal family and win, but the RFs strategy of: keep quiet, don't complain, do your duty, gossip is transitory, really has shown it's strength.
