Or put another way, the truth matters.
Harry's conceited idea that his own "truth" is what counts turned out to have a cost. His father was cornered into reacting because Harry's self-pitying moans made the king look weak. His toxic semi-truths casting himself as a victim caused real harm. And he insulted Charles' wife.
So now Harry has no grace-and-favour home in the UK. And nearly everyone here is thrilled. Hopefully all of the other privileges from which Prince Arsehole benefits will be removed. He contributes nothing to the monarchy. He clearly doesn't understand its purpose.
He is what they call a wrong 'un.
