I read this on another forum:
The story is that their being denied permission to run their own 'court' was one of the triggers of Mexit. There are 3 royal courts - Kensington Palace (the Cambridges), Clarence House (Charles and Camila) and Buckingham Palace (HM and basically all the assorted other royals). All 3 run their media operations fairly independently of one another. Supposedly the Sussexes felt that they deserved their own court (Toad Hall Royal?) but were told that only the heirs got that so... no. They would be part of the BP set-up along with Ann, Edward, Sophie etc.
Naturally that wasn't good enough for the dasterdly duo, so they set up 'Sussex Royal' as their attempt at doing their own thing, even though it never had the status of a royal court. Now, with Mexit, they're being denied the use of that, and rightly so. I also wonder why they haven't got their own social media by now however. Could it be that the palace are keeping them on an even tighter leash than we had supposed?
^The three operations, BP, CH, KP are each a 'court' indeed; each also represents a specific 'arm' of the RF with it's own clear place, function, activities, future. The Monarch, The Heir, The Heir Presumptive. Each is a part of the whole.
And the logic obviously is that - as you said - everyone outside of this is then dumped together, so to speak, in one basket (Anne, Edward & Sophie, Andrew when he was still active etc) which operates under the overall monarchial BP umbrella - but only in connection with their official duties as working royals.
If anyone had been thinking of this - and I mean us 'civilians' - we would automatically have assumed that eventually Harry and his wife would be working under this set-up, just like Edward and Sophie; the two people whose life most closely pointed the way to what Harry could have expected his long-term future to be.
And now, when we look back to what Harry and Meghan were saying, starting with the engagement interview, how they clearly envisioned their future - well, it becomes obvious that this was yet again one thing Harry had never explained to Meghan at the outset.
Or maybe he had his own Cunning Plan, maybe he thought that precisely because Meghan was this Superior Glam Professional Woman, he could use her arrival to subvert this arrangement when it came to the two of them.
'Hit the ground runnin'; 'Voice being heard' blah blah - it's obvious Meghan absolutely thought she and Harry would have an operation within the family that would be a sort of Royal version of the Clinton Foundation. In no way was she aware of the fact that she'd be subsumed into a group of second-or third tier minor royals - and she certainly wasn't going to accept that.
That idea of a 'voice being heard' was I believe, something very concrete for her. She absolutely saw herself standing on some grand stage, spotlights trained on her, giving a speech to some UN-like outfit on Important Global Subjects. And to go together with this life, they would obviously have a social media platform that beat the drum for them, one that would enhance their brand, their position and attract other internationally-adored people of power and influence to them, wanting to work with them, further expanding their reach.
I believe that this was very much the Alternate Court Harry - and Meghan - had in mind, the one that was going to completely overshadow William and Kate, leaving them behind in the dust, looking like two provincials playing around in a very small dated duck pond.
They tried to get all this off the ground in various ways, culminating in the long Vancouver Christmas hols when they wrote the manifesto, thinking they could strong-arm TQ into creating a framework where they could have this Court of theirs slightly outside the family, since they were barred from having it fully inside it.
And here we are, examining the wreckage that is the result. As many here have pointed out, Harry could not possibly ever have imagined how quickly and how thoroughly it would all go to hell in a handcart.^
