That's because H&M don't have any beef with any of them. Well, maybe Princess Anne over Frogmore, but she did seem to be quite kind to Harry when the Queen died (red feather excepted).
The fundamental narrative is:
William got all the sausages in life. That's not fair. Mummy said we should share everything. I am always held back because of this. William is a power hungry beast who didn't listen to mummy about sharing with me; and
Catherine is a dimwit, talentless nobody who bagged the big prize. That's not fair. What's so special about her? Nothing. There were better candidates for the job, who could have made the RF fit for the future. She's really not very good at it, she can't do speeches and isn't a serious feminist like some of us are.
The dismal record of women who married in? Well there was Diana, a naive teenager caught up in a marriage of convenience and her own mental health issues, affairs and wanting to break away. Nobody thought she was disposable, the RF didn't want her and Charles to divorce, until her public complaining made things untenable. Her death had nothing to do with the RF.
Sarah Ferguson, whose divorce had nothing to do with anybody other than her and Andrew - she wanted to work and could not do so as a princess. Most of her bad press came not from the RF, but her own antics, like toe sucking with her financial adviser. And in any event, her ex never treated her as disposable, he clearly has a huge amount of affection for her and continued co-habiting with her, and the Queen apparently really liked her. Only Philip seemed to dislike her.
Sophie, who after a rocky start (again, self inflicted), became an absolutely solid and beloved member of the RF, the Queen treated her like her own daughter.
After that is was Catherine and then Meghan. Going further back, it was Wallis Simpson (surely nobody is feeling like she was hard done by), and Elizabeth Bowes-Lyon, who was George VI's rock and became the beloved Queen Mother.
