It seems to me that Beatrice and Eugenie for that matter, support causes close to their hearts. That the should also tag team with their Dad's pet project is no surprise. As mentioned, both of these girls go about their business with grace and happiness and are very popular.
For some reason Beatrice and Eugenie really get the snarky treatment, even here on this thread, be it about whether or not they work (none of our business) and of course there is endless bile about their fashion which, to be honest, is totally unfair.
As to their being considered surplus to royal requirements by their Uncle Charles as per the great "Slimming Down the Monarchy" debate, well we finally have had some sort of verification that someone close to Prince Charles "inimated" to someone in the media that it "might" happen around 18 - 20 years ago!
Don't know about anybody else but my world has moved and changed a lot over the last 20 years. Mostly in ways I could never have imagined or planned for. Technology has changed the way we work, the way we communicate, the way we go about the business of living.
Surely the same is true of the BRF. 20 years ago Britannia still ruled the waves, now it's a tourist attraction. Whoever would have imagined that 20 years ago! William, Harry, Beatrice and Eugenie were still children, their parents still married. 20 years ago who would have imagined the shape of the BRF as it is today. Would they have imagined separations, divorce, even death? Would they have imagined both Prince Philip and Queen Elizabeth not only alive but still kicking.
The point is that decisions and aspirations for the future have to remain flexible because who knows what tomorrow will bring. Nothing is graven in stone. Least of all the futures of the youngest generation of the BRF.
