The “Forced Out” narrative is a stretch when we all know the timeline here, and what each party said and did.
As mentioned upthread, the whole process was kicked off by the Sussex Royal announcement where they announced they intended to “carve out a progressive new role”, and valued the chance to earn a private income which they currently were not allowed to do. But they still looked forward to representing the Royal family and collaborating with the Queen.
Then came the Sandringham summit. The Queen said after that “Harry and Meghan have made clear that they do not want to be reliant on public funds in their new lives. It has therefore been agreed that there will be a period of transition in which the Sussexes will spend time in Canada and the UK”
Meghan and Harry appeared to be somewhat annoyed at the transitional arrangements, saying on their website: “While there is precedent for other titled members of the Royal Family to seek employment outside of the institution, for The Duke and Duchess of Sussex, a 12-month review period has been put in place.”
Journalist Tom Bradby (he did the “not many people have asked if I’m okay” interview in South Africa) was quoted in People as a “friend of the couple” warning that “should a suitable solution not be reached, the royal couple could give a no-holds-barred interview. I have some idea of what might be aired in a full, no-holds-barred sit down interview and I don’t think it would be pretty,”
So, they announced they were leaving, and the manner of their leaving, got pushback from the Palace, hammered out an agreement which they seemed less than happy with, but left anyway, while making threats that they could seek revenge for this (which they did, as we know). And they themselves expressed this as them “Finding Freedom” - i.e. something that they very much wanted.
