Contrary to what she says, it appears Megan may have been very knowledgeable regarding the Windsors. Lady C posted this excellent information:

Gorgeous Lady C. Thanks for sending.
I was 7 minutes in before cutting away from Lady C, whom I thought was falling victim to exactly what she was attributing to Meghan.
Eg, a generous beginning toward the Duchess and charitable, before then sinking claws, assigning motives to Meghan and crawling around in her head for insidious thoughts and plots that will never be proven.
And, the lovely Lady is hawking her book. Sweet.
