Either Meghan is unbelievably picky and turns down everything, or the rumours that she's impossible to work with are true.
I think it's something else. I think she's trying to keep all options open. She won't do anything that would further link her to the RF (has to turn the page on all that) OR damage her links to it (for her sake, Harry's sake, the children's sake, whatever - birthright blah blah). But she has nothing else, so is left doing the most bland of bland things.
Someone, somewhere, would be able to make money off Meghan. She has a huge profile, she's easy on the eye. Managed correctly, there could be something good there. History is littered with difficult characters, and people will do a LOT to make good dollar. But I think she feels she has to toe a line. I think she thinks there's not much available to her that is befitting of a Duchess in exile with a Prince and Princess for children. I mean, the obvious answer is to stay out of the public eye, but that's not for our Megs.
That said, I can also believe she's picky. I see parallels between her and - stay with me! - Trump. His 2024 win and her UK presence in the run up to and right after her wedding were both moments when, if the papers are to believed, they both felt like they had the world in the palm of their hands. They felt universally loved and adored and in her case envied, regardless of any facts to the contrary. The power must be intoxicating. Nobody is going to come down from that easily.
