I think the royal reporters know the reality, but were overjoyed by the “hero Harry” pr drive and are happy that the royal family is getting more attention. This is, after all, their bread and butter.
I think they know it’s all an act, but they want the act to be successful because they profit from it. That’s why they were all so complimentary about Meghan’s supposed “ease” with the media coverage and the supposed professionalism that she was going to bring to KP. Unfortunately, right now the act is failing, the professionalism was her Hollywood pr agency and not her, and the whole thing is falling apart.
