Maybe yes, maybe no as far as the corroborating witnesses go. Bear in mind that the behind the scenes palace bureaucracy is an old, tangled, and nebulous power structure that has been wielding authority of a somewhat murky nature for many, many years -- even to some extent over the royals themselves. In a legal arena this would qualify for special scrutiny to attempt to evaluate if the corroboration wasn't simply the by-product of conspirators acting in concert. I'm not saying that is the case, I'm simply saying it has to be considered if the whole thing is going to be investigated to uncover facts and come to conclusions based on facts, whatever they may be.
My bet is that there's blame to share and both sides have dirty hands. Commence the quibbling over -- "She started it!" "No, they did this to me first!" I suspect Harry knows this and is either refusing to acknowledge it or is being willfully blind. Either way, he's the one person with the most power to have controlled this situation from the start, something he would have done if he did indeed truly love his birth family as much as he says he does. If his wife has even a small bit of the negative qualities and calculating nature she has been accused of, Harry is a complete fool because he will either live his life under her thumb or in a no man's land he will have helped construct for himself, separated from his birth family and potentially his children for significant portions of time.
