The press has an appalling track record for its treatment of female joiners to the Royal Family. Anyone old enough will remember the headlines about Fergie - accused of being too brash, overweight etc.
Immediately before she was killed, Diana was the subject of intense vitriol for her relationship with Dodi (of course all the journalists backtracked sharply after her death, but there were some red faces from those whose scathing articles had gone to press before the tragedy).
Camilla was scorned because she was middle-aged and average-looking, and journalists felt entitled to take a moral high ground because infidelity was involved.
Kate went through years of being dubbed 'waity Katy' before William made up his mind to marry her.
Meghan is the latest victim and one can't blame her for trying to escape it all. I imagine she and Harry anticipated the media storm surrounding their departure, but saw it as a necessary evil.
