I recently ordered a book of a very sensitive nature, politically, lol.
I was waiting to see if my credit card would decline for no reason, or if the bookstore would accept the order for a moment, then send an e-mail, “sorry, we made a mistake, it’s out of stock.”
Alas, none of that has happened and the book has shipped. I have no intriguing story to tell at this point unless it gets disappeared in transit.
As long as a writer can get something published in the first place, I don’t think books are at the highest levels of interest for censorship. Nobody reads those things anyway, so why bother. 😬
