Personally I think C&W would be wise to do nothing.
Any attempt to remove titles will just add more drama to the Sussex narrative of continual victimhood.
Ultimately H&M can only sell the same story so many times before it has no value - there is absolutely no point in giving them another chapter for a book or premise for another so-called documentary (so-called because it's a PR piece of their version of events without any push back/balance).
I feel H&M have made a big mistake in how they have approached their exit from the RF.
I don't blame them for wanting a different life, but they strike me as highly impulsive, quick to circle the wagons and unwilling/unable think about the longer term consequences of their approach.
It's been years now since they left the RF and the Netflix/book deal will bleed them dry on "inside info".
What then? Other deals such as Pearl have been pulled and Netflix's subscriptions are on a downturn.
Yes the viewing figure are good - but at what cost?
H's family relations are dust I would imagine bit think beyond that.
H&M are trying to cultivate a megawatt brand and to do that you need to be "in" with the movers and shakers - many of with are tellingly absent from their TV show and they notably have not been invited to key events high profile events you might expect they would have been a shoo in for (Obama birthdays, Met Gala etc).
I can't help wonder if you were an A lister (protective of your brand and privacy) just how wary you would be in befriending a couple prepared to sell out their own family for £££. If I was Beyoncé or Michelle I wouldn't be inviting them to dinner for fear I'd just be another "episode".
I can't see this ending well, even if the series and book are a success and I think that's sad.
They both had an amazing opportunity both within the RF and outside it, yet they seem to continue with a very reactive and short term perspective of their situation.
