Probably you haven't lost out on anything, actually. The Twins are Nancy and Stephanie Sidley, who didn't approve Meghan and Harry's lies and disrespect towards the late Queen and Prince Philip and all the rest. They live in the States and explain some 'aspects' (like no-one gets paparazzi-pictured in an airport unless the 'celebrity' informs the photographers to be there, because the airport security wouldn't allow them hang around for hours).
So, they have their youtube channel, and actually I quite like them, but Ex-Ascot finds it hard to listen to them - and they really do speak fast and emotionally, but in my mind it's kinda-sweet. Plus, they do have a point, and I'm not the only one who thinks so.
Also, I don't know anything much about the ... pop-culture? of their 'age group', as they put it, so glimpses into it are interesting for me, as they explain things. AND they don't do it for money, no commercials, just a 'boost' to an animal charity at the end of the video.
They say as the mainstream media never asks the hard questions or challenge the Sussexes, someone has to do it, and they are one of the some that are quite good, allegedly.
For example, in this one they tear the US-magazine article on Meghan to shreds, if you'd like to get a sample.
