Sadly, the media needs a target. Kate was that for years but it switched to Meghan at some point. Her coverage was extremely positive at the beginning. I see people saying that the palace never defended her but do other members of the family. The palace rarely defends anyone. Kate was accused of having an eating disorder for years, had trouble getting pregnant, was blamed for a nurse committing suicide,... and the palace stayed silent the whole time.
With Meghan, while she obviously faced some racism (straight out of compton headline, a journalist comparing Archie to a monkey on Twitter [he wad later fired and interrogated by the police]), Meghan only worked 72 days as a royal and the palace released 20 statement denying stories in the press. I don't even remember the palace putting out that many statements in a year and a half for other royals.
I think that the palace then stopped because many of the stories were true. KP even lied twice to protect them. The Blood earrings, gifted by a Saudi prince that allegedly killed a journalist. She even wore them the day after the assassination and KP lied for her, saying that it was a loan.
Also, KP lied saying that one of her staff members left because she moved to another country when it fact she was one of the employees that accused her of bullying. Harry did confirmed the bullying in his book saying that several of their employees were weeping at their desks
Then them getting bashed for taking private jets while preaching about climate change,...
