Camilla had an awful time with the press.
Yes they had some effort to show their relationship as a love story (they do seem genuine in their care for each other and if he'd been the spare could probably have settled with her in the first place) but I think it over estimates the control anyone has over the media.
Camilla will have friendly journalists. They all will but it's more in the sense of providing official stories first etc.
Slagging off Meghan didn't serve a purpose for any of them. Camilla is very reserved and doesn't court much of this. Her image has been rehabilitated largely because she's stuck her head down, worked and not caused many issues. Much like Kate and Sophie. The fact they have been in a relationship so long has thawed the views of many towards her but she understood she had to give it time.
Harry and Meghan seem to lack this understanding. If she had got on and worked things would have died down. They'd always be stories but the intensity would diminish.
Kate has been slagged off plenty as have her family. Every royal event prompted money grabbing stories about the family business. Her mother is always described as social climbing. It's been inferred she was sent to st Andrews purely to snare a prince.
Meghan and Harry seem unable to grasp the idea that there's a time and a place. It was Meghan's undoing on the south Africa trip. It was all pretty positive til she did the 'no one's asked how I was'.
Fine in a London interview, totally ridiculous when you've just visited a slum.
Both failed to listen to the pr advice they were given, don't understand that seeking to correct rumours merely confirms their truth and view this as 'being thrown under the bus' rather than the reality that ignoring it is the quickest way to make it go away
