It might. But not much.
"Waity-Katie" was in the papers for YEARS with not much positive about her because she wasn't married yet she was essentially pretending at working while "waiting". She basically only started to get more consistently good coverage when MM became the new girl.
Princesses Béatrice and Euginie had quite a lot of horrible press about the way they looked, be it "unflattering" (I thought "normal") photos of one of them in swimwear just after she turned 18, or them also doing nothing much other than riding in coattails. It's dampened down over the years too.
Prince Charles barely has any run of good press. He's had a lifetime of being a national joke. Now there's an attempt to turn that around, but the damage runs deep.
Diana also had shocking news coverage for a long time.
And Sarah Ferguson, well my god. I can't think of anybody who has been ridiculed so much across basically every press outlet. I'm not actually sure how she survived. She attempted to break free from it with a life in the states, but was ridiculed about that too. And virtually every article about her for years and years and years talked about her appearance - and none of it positive. The fat shaming she got wasn't even subtle. For years.
I am not a follower of the RF, but I'm not blind to photos and headlines and am commenting on the general trends in reporting of these people.
MM is, if anything, being treated with kid gloves in comparison to how the above were dealt with in the press. I'm not saying that's a high bar to measure against, but she's certainly not being treated worse than them. And yet she's actually done and continues to do things that put her in the public eye and link her to the RF.
I get there's dog whistle racist remarks in a few articles - a few - and that's a whole other level of unacceptable. But criticism of her actions and even ridicule of her actions is not the same thing as racism at all, because in the context of reporting on the RF, she has done FAR more than the others to warrant coverage (moving abroad, interview with Oprah etc), plus ACTIVELY seeks it (publishing a book, contributing to books, signing with Netflix, making a podcast - these are things that all involve press attention for ratings/income streams).
