I'm from the UK and not really a royalist per se , but I found it rather nauseating. As soon as the interview began , with Oprah talking about Meghan discussing "her truths" , it was clear that any degree of objectivity or any challenging , even mildly , some of her statements were not on the menu. Some of the things she said ( for example , despite what she implied - there never was any possibility that Archie was going to be a Prince ) were definite lies - I think she was relying on the US audience to take things first hand without really knowing the facts.
Another guy lost / resigned his job as well here , as well as Piers Morgan. Its interesting to watch his interview that led to a "revenge of the wokes" type backlash that cost him his job. https://www.dailymail.co.uk/news/article-9348267/Society-Editors-chief-resigns-criticism-defending-UK-press-against-racism-claims.html
It has exposed a bit gulf in attitudes in the UK which somewhat mirrors that in the USA and peoples' attitudes largely depends on their age.
