I read a chapter of Spare every time I went into Asda, and was struck by how different the prose is from the verbiosity on the Archwell website.
I agree with @Wherestheheatwave that Spare itself has a shift of prose styles, but it mostly IS prose (controlled to some extent by the ghost writer) and not prolix.
I just despair of this over-blown, pompous crap on the website.
Archewell Audio is the newly formed, audio-first production company started by The Duke and Duchess of Sussex. Archewell Audio will produce programming that uplifts and entertains audiences around the world. Under an exclusive partnership, Archewell Audio will join Spotify and their global reach—180 million Premium subscribers and 406 million monthly active users around the world—to spotlight diverse perspectives and voices. As part of the partnership, The Duke and Duchess through Archewell Audio produce podcasts and shows that build community through shared experiences, powerful narratives, and universal values.
If you click the link you get some guff from the now departed Dawn Ostroff about “The Duke and Duchess of Sussex may live in California, but the power of their voices rests in their status as citizens of the world,” and the usual "global platform" allusions.
(And yes, it's out of date too. Is the Archewell website not updated?)
