I wasn't suggesting she didn't want the public wedding, or that she did. I merely said that the anecdote about the backyard wedding may have been an indirect way of addressing criticism they've seen about the lavish spectacle of a wedding, the spending, etc., etc. Do I know that to be the case? No. What makes me think it is likely is it fits with the pattern they are establishing with what they say, how they say it, and the way they choose to frame the situation that they present publicly. It's as if they are telling the public, this is us, raw, unvarnished, real, genuine -- and yet they've smeared the camera lens with Vaseline and have photoshopped the daylights out of the images.
Let's face it, if they had told the family and the palace that they wanted a smaller, intimate wedding the only response that would have been possible would have been, it is necessary that you go through with the large public ceremony and celebration, both as the son/brother of future kings and your mother's son, and because your bride is American and of mixed race. There would have been no quieting the clamor if Diana's second son didn't get the pageantry, and there would have been plenty of blowback if the American bride of mixed race wasn't given the chance to wear a tiara on a very public stage. Nothing the royals or even Harry and Meghan themselves might have said would have quieted all doubts about who wanted a small private wedding.
