Unfortunately I have to say I agree. The hard part is getting a PR team that is schooled in 'ethics over spin' and understand's that they are dealing with a family, not a firm. That it is essential to preserve the family's sense of decency. For example, we over on the Swedish threads, are forever bemoaning the hopeless PR. It's enough to make you wince.
As to Charles, Camilla, William and Harry? On those very few occasions that they have actually participated in a one on one interview, one of Harry's stands out. He said something along the lines of "she makes our father happy, we love her to bits".
Harry did not look or sound tense, his speech and diction were animated and, most important of all, he could have just smiled and said "she makes our father happy and that's okay", but he didn't. Harry comes across as not nearly as tightly wound as William, which is not to say that he relaxes and enjoys the media, which makes his statement all the more telling.
So basically, all this "scandal", "exploitation", etc. is, to me, just so much media hype because, let's face it, a 'wicked stepmother' is so much more "newsworthy" than Charles and Camilla happily, if boringly, married and each with liked and likeable stepchildren.
