This couple had a right to respond to all the attacks / character assassination that they've had in the press. If the Palace feel unhappy about that, then perhaps they should reflect that they ought to have used their considerable influence to intervene before their lives became unbearable. Instead, they fanned the flames by leaking negative stories.
The way the Palace has clearly mobilised to attack them after this interview is toxic and repugnant. Anyone with half a brain can see that there is no substance to all the negative stories that get printed about them. Why would I want to buy a newspaper that smears anyone because of their race? Going after a pregnant woman too... the shame of it!
