I think there is a tendency to portray her as a helpless victim in many threads on this forum. While it's true that the press has given her a very hard time, the British tabloid press gives everyone a very hard time, but usually turns its fire elsewhere after enough time has passed. Unfortunately, Meghan's family provided way too much fodder, which is not her fault, but it's not like the press was just making up the looney-tunes aspects of her family.
So far as her friends speaking out goes, I don't think it helps much at all since by having them speak out on programs such as Meghan and Harry Plus One (American) or in People magazine (American) it's pretty clear that the target audience is not the British people, which, you know, are the people the Sussexes should actually be concerned about. It's the American audience/fan base, and I'm not convinced that is a wise move in the long run.
Royals have used friends to put out the story they want for a long time, with wildly varying degrees of success, so if that's the route they want to go, it might be worthwhile for the Sussexes to actually do that where they live, which is why I suggested that making an effort to develop a more positive relationship with the British press might pay off in the long term. Giving special access to American publications and media might be one in the eye for the British press, but it certainly won't help in the long term. What's the long term objective, here, and how does it serve what they want to accomplish? That's the question.
