The answer to that is simple. Read the thread again about him starting to write the book. When he was first writing it, he made it clear that he was going to try his hardest to get his book published by a publisher. He spoke about “sample chapters” to be sent to publishers and asked for advice from writers on this forum who have been published before. Of course people were encouraging him to do this.
What eventually happened was very different from how he presented it in that thread. Say if he had started the thread off thus:
“I want to write a book about JWs and my life. After much effort, no publisher has been willing to pick up and fund this endeavour of mine. I am quitting my job to focus on working on these books and videos fullltime. Therefore I am asking that all of you donate to me so I can make this happen. My second book will include the provision of having your story re-told and published by me for the discounted price of $150. You will also have your picture taken with me, Lloyd Evans, for paying for this “perk”. This is my way of rewarding many of you in my important work of saving JWs. To donate, please go to the website...”
Suffice it to say the response wouldn’t have been anywhere nearly as supportive as the thread you see there. Keep in mind that at the time he announced the book he was still proofreading his wife’s translation work for a living.
