While photos of child sex abuse are of course never acceptable and anyone taking them, looking at them and sharing them should be dealt with appropriately , I would point out that using photos of your children to monetise your commercial interests -even if you are careful not to show their faces - is also a form of exploitation.
HaM know that their most valuable assets are their children’s faces, I do wonder how soon it will be before they give in to the temptation and sell tasteful pictures of them to the highest bidder. If they can also get their Royal Grandad into the shot then kerching, big payday. HaM must be steaming that the RF has so far wisely kept control of the “King meets grandchildren” photos.
