I am honestly baffled how people can hear something about someone in the media, and decide it’s gospel truth.
Harry & Meghan over-exposed themselves, though. People are forming their views based on H&M's own words in the interviews with Oprah Winfrey, Tom Bradby, Anderson Cooper, Andrew Sorkin, Jane Pauley etc; the whole of the Netflix series; Spare; and various other magazine interviews (taped), TV appearances (on record), and 'red carpet' interviews.
So people have a great deal to mull over that are primary sources, not merely the secondary and tertiary sources you imply.
