She doesn’t approve of young royals trying to change things
I think if that were true she would be being a bit hypocritical.
She 'changed things' when she was a young royal by determinedly pursuing excellence in her chosen field of eventing and competing at a very high level. I can't think of any other royal who has turned what would just be a hobby sport into a serious competitive endeavour.
She, admittedly following her aunt's precedent, married a commoner and refused to allow her children to be sucked into the Royalty circus. As a consequence they have pretty 'normal' lives (within the parameters of the 'class' they exist in).
Not such an extreme change as H &M, but a significant change nonetheless. It's small steps for each generation.
(I have to confess that, as a bit of a horsey person, I think very highly of her and Zara)
