If you care about the book bestseller lists, why doesn’t this book cover look like previous bestsellers? To get a sense of how those look like, here is an “interactive map of over 5,000 book covers” from the NYT “Best Selling” and “Also Selling” lists between 2008 and 2019.
Most of those are fiction or biographies/memoirs (which often have a picture of the subject/author on the cover), which seem to have a different cover style than other books. Skimming through some lists of NYT bestsellers, some books with the most comparable “Really Big Thing!” topics are “Fascism: A Warning” (Madeleine Albright, cover has large red-on-black lettering, no imagery), “How to Avoid a Climate Disaster” (Bill Gates, cover has large gradiented blue-to-red text on white background, author above, subtitle below, no imagery), “Germs” (title in centered large black lettering, subtitle “Biological Weapons and America’s Secret War” in smaller text above, authors beneath; background is a white surface with a diagonally-oriented glass slide on it), and “A Warning—Anonymous” (plain black text on white background, subtitle “A Senior Trump Administration Official” in small red lettering below, no imagery). Neither cover version of IABIED looks that different from that pattern, I think.
