These publishers’ names are:
Hachette,
Penguin Random House,
Wiley,
and
HarperCollins
Time to never buy any book from them again. I’m moving on to pirating ebooks and audiobooks. Sorry JRR and Christopher Tolkien (may you rest in peace), but I’m not buying any more of your books because they were published by HarperCollins. And I’m also not buying a lot of other books too.
I really appreciate the sentiment, but sadly: Individual boycots that aren’t attached to a concertated campaign sadly don’t work. Pirate away, but you can be certain that these publishers don’t know that you exist.
I would argue this is actually one of the most effective ways to respond. If enough people do it then the company has to react somehow (by pivoting, etc.). Obviously an organized effort would be better, but the “vote with your money” method isn’t anything to ridicule.
