You are right on the economics @Serenster
It absolutely boggles the mind that we hear all the time how unpopular M and H are, and how popular the other royals are, yet it is H and M who drive the media narratives on the Royal Family.
H and M are the only reason most people, especially outside the UK, are interested in the Royal Family at all . Even this thread was stated because Meghan had not been seen in public in two or so months.
Everything they do is slammed, even as they drive up clicks, and sales of newspapers, coffee, books, clothes whatever they touch and are associated with.
They have made careers for people, Morgan and Wooton increased their bank balances by writing column after column about Meghan, Camilla Tominey rose from being a minor reporter at the daily Star to the Daily Telegraph, all on Meghan's back, Angela Levin's entire livelihood depends on them, Tom Bower wrote his only commercially successful book about them, they drive the threads here on Mumsnet.
We can argue about what it is about them that interests so many people while being apparently so unpopular in the polls but there is no denying that there is an industry centred around them.
And if others are going to benefit from throwing their names around, damn straight they should benefit from being themselves.
