You know what this is all about. Meghan started to get too much attention early on, the firm, be it Kate, William or their advisors and teams within 'the firm' felt threatened by it. William, Charles and the advisors are only bothered about the succession, not the minor royals. So they kicked back by leaking negative stuff out to the press. They created pressure on her internally with the colour of the baby stuff, and that obviously would take attention away from Williams and Kate's own kids who they will deem more important as next in line.
At the end of the day, this all just highlights the duplicitousness, the cruelty, the ruthlessness of royalty. In one way they've got off lightly, I mean she would have been killed and Harry would have disappeared to the tower 400 years ago, that's what they do, the ruthlessness of cutting out their own brother/son in Harry and trying to wreck his marriage is just what royals do to win. They did far worse in the past. Even in the recent past Edward was ostracised for many years after Wallace came along, and well Diana was treated appallingly for being angry at being cheated on.
Good luck to Harry, and Meghan, they are free from this mess. I feel for Harry being estranged from his brother and Dad, but until they apologise that will always be the case, and Kings in waiting don't tend to back down. They have made themselves a plan, have an opportunity for a life more free than it could ever be in England, and anyone that wishes them ill for walking away needs to take a good look at themselves.
