From Simon & Schuster, a large relevant publisher who wrote her a fat advance check, down to PublicAffairs, a social studies/feminist publisher. Weirder still, they directly publish European globalist and generally reviled jew George Soros, their web front page points to The Economist, a weekly business publication basically owned directly by the Rothschilds. You can't make this shit up if you tried.
On a more mundane level, the reasons for switching publishers can be numerous and complicated. Here's a few plebbitor's takes of switching book publishers on non-related titles:
>It will depend on who owns the copyright. If they own it, the new publisher will have to buy the IP rights from them, which might make it difficult to first find a publisher who is interested. If you own the IP rights, and they don't have a contractual right of first refusal, then you can shop it around to anyone or self-publish it.
>My book contract has a non-competition clause to prevent me from publishing a similar work with a different publisher that would hurt their sales. But I have a termination clause once sales decline too low.
>But if they're not interested in the book, you could ask them to revert all rights to you.
Odds are preorders are so low/interest so bad despite the Amy Pascal movie deal, that Simon & Schuster are washing their hands of the whole affair and Chelsea is calling in jewish favors to make sure the book is published with a smaller on-demand run so it's less embarrassing when it releases and no one reads it publicly in all the right places.
