Interesting about the royal foundation. Actually, I don't think it's a bad thing, necessarily. As the article points out, the Cambridges have a constitutional role - they're bound by that. There are things they cannot say or do, ever, no matter how much they may want to, because of it. However Harry and Meghan aren't bound in that way, and can be more political and more radical, if they wish. And why shouldn't they, if they can? I would hate to be gagged in the way the Cambridges effectively are. And I'd also hate to be subordinate to a sibling based only on the accident of our birth order. I'm not suggesting that H&M are planning the next Wars of the Roses or anything, but having to defer at work to your big brother must be hard, if you have your own ideas and passions to follow.
Even without that dynamic, working with family is hard - splitting the personal and professional could be a big step towards healing any 'rift'.
