I got this scary response:
"The interior file submitted for this title contains text referencing Amazon.com. Please remove all text and/or logos which reference Amazon.com."
Years ago, the USSR forbade published criticism of the Communist Party, but I am shocked to find that an American printer/publisher/bookseller wants to censor a writer.
I'll have the book printed by Lightning Source, instead. It will cost me a little more upfront, but I'll probably make more money, and I won't have a reincarnation of the KGB peering over my shoulder as I type.
Interestingly, CreateSpace had absolutely no objection to printing and distributing a previous book I wrote that was critical of its competitor, Outskirts Press. That book mentions Amazon.com many times. Many other books printed and/or published by CreateSpace also mention Amazon.com -- even in their titles.
