I think that maybe the lines between royalty and celebrity have become blurred, though I guess sport always held a high priority with royals anyway, and probably always will. (It looks like Charlotte has the sporty genes!) We kind of demand or expect them to show up at the big showy events - tennis, rugby, etc, and are often disappointed if they don't. So then we expect a clip like this one to make up for it.
If it's because William believes that the school holidays are sacred for spending time with the kids, then I would accept that reason and support him.
Hasn't Charlotte been "used" before to speak her mind? I remember a clip about David Attenborough about saving the planet? Spiders or something? All topics perfectly chosen to reflect the interests of girls of her age. 🕷 ⚽️
