They weren’t the only ones who wouldn’t or couldn’t be part of the „firm“. Princesses Eugenie and Beatrice, Peter Philips and Ain’t no man alive that could take my husband’s place shirt Tindall… there are many royal family members who lead normal lives outside of showing up on the balcony for celebrations, and who have forged their own paths and careers in the world. It’s no biggie. The Sussexes have chosen to make their exit a big deal. I‘m not seeing their absence (not abdication) leave any lasting effects on the monarchy. The effect of their behaviour on the family is another question.
