Another take on you post on why they left.
According to the timelines.
Yes, H&M were doing very well with their duties, infact a bit too well. Disturbing the status quo, after all the ones in line to be king are supposed to shine. Someone took exception and leaked lies to the media - none of this Prince of Hearts nonsense for MM. Being a hungry beast, the media needed more and more. Till it all got out of hand. H&M were not happy with this, obviously.
In the meantime, within the palace someone raises concerns about the baby's skin tone, at the same time H&M are told that their babies will not be Prince and Princess. This is apparently due to slim down, too many prince/ess apparently, despite the fact that the palace went out of their way to change Charlotte and Louis - instead of saying first born is to be titled wether boy or girl and we just stick to that line. So H&M figure, too many princes is not the problem here. What if W&K had 5 children. Also the rule is not extended to H himself who may have had his own 6 children. So at the time of the rule, you never know if there could eventually be 11 prince/es.
To top it off they are told that because of this lack of prince title, the baby will not have protection. H&M ask why, no answer (they are well aware that security is about threat, from the Met because H did ask that question on an unrelated matter). They are well aware at this point that the palace can alter rules as they wish.
Archie is born, and without consultation, he is titled Master. A statement is put out as such, with a brief that H&M wanted it so to protect the baby. Except, they never said any such thing.
At this point H&M realise that it could well be a reality that LPs really could be changed for their DC.
They ask themselves, what is the point of them being senior working royals and getting the brunt of the criticism, working at a senior level with all the threats, when babies will not even be protected. They could be like the cousins B&E etc. They can go out make a living (does not have to be a 9-5, could be different projects like the Philipps etc.), but they will be there if HMQ needs them for something. Sussex Royal umbrella will take care of the existing charities if need be. They will set up shop on CW country of Canada to make working together easy.
They are told, eff off, you are either in or out. No changes are made.
So they set off.
They are given an extension of a year. They spend that time wrapping things up with the charities etc. - it's Covid, so mostly phone calls, zoom and letters. They are still doing their job for another year - till 2021. They pay off Frogmore and rent. Brainstorm.
PC cuts the funds and security. H asks if the risk has been assessed as lowered. No. They scramble around. Tyler Perry to the rescue - come live at my empty house and security will be provided. (I have to say at this point that PC was likely instructed at this point to cut the funds, don't think he would have just done in personally, with a grandchild this young). Yes, they go. Advice from old friends about a way forward. Netflix, Spotify etc. are concluded.
H&M were hurt that security was taken from baby Archie definitely, and were also hurt by what they saw as racism against him. What parent would not be. They were not whinging and complaining. They had resigned themselves to what took place. There were lots of questions about why they left. I think they just came to recount a certain time and the events that took place.
