They had the opportunity to remove them from public life and instead they chose to use them publicly to boost their own image.
Absolutely. These children could have grown up in complete privacy. How often do we see Eugenie or Beatrice's children? Pretty much never. And they're the valid comparison, not the Wales children who do have a role in British public life.
And I'm not even sure that releasing photos of the kids do 'boost' their parents' image. The photos are so soulless and the back of the head thing is borderline creepy, not to mention hypocritical. The photo of Lili kneeling on the ground while Meghan prepared to jet off without her yet again was a new low. They'd be much better off not showing the kids at all as they’re not fooling anything with this back of the head nonsense. They might get some respect for that, and that's something they badly need.
