Name one instance where that worked when it wasn’t connected to a massive public outcry. Do you remember the Call of Duty “boycott”? Ubisoft is still in business, too.
Also, the majority of book buyers don’t know or care about this verdict.
Also also: The publishers won’t even be able to correlate the “lost” revenue of individual people boycotting with their shitty behavior. It’s not “Oh, we sold 1000 less copies of this book than expected, because we fought the archive.” It’s more: “Our predictions were off by 1000 copies. No idea if that’s because of some tangible factor, or just ‘noise’.”
