I think the problem is that it isn't what she wanted to do. She had visions of herself as a globe trotting philanthropist, taking private jets to gala dinners where she'd give well received speeches while wearing custom couture and rubbing shoulders with world leaders. That didn't quite work out, however, so now here she is sprinkling edible flowers on elevated sandwiches. The claim that she was somehow 'stopped' from doing so is just a way of pretending that this is what she wanted all along, when it clearly isn't.
Fundamentally this is the problem. Where she is now (well both of them) isn't where she wanted them to be. I think she very much did see herself as globe trotting and giving well received speeches to a variety of audiences.
But it's all about the content. Even when she has given speeches it's full of soundbites and no substance and the dreadful word salad that actually doesn't mean anything.
Even this latest endeavour has poor content, nothing new, nothing inspirational, no interesting practical hacks just nothing really but much love and admiration for Meghan delivered in a very fake setting in a very fake way.
When people watch a programme they want to be entertained or informed or amused or at the very least interested in the content. I can't see a future for her peddling this as it's so lacking in anything of substance.
