That's how I read this too. The publisher invested a non-trivial amount of work and was left with nothing, for no better reason than the author changed their mind. From the tone of the post, the author seems to not realize or care.
The publisher changed their mind, too. I don’t think the author was pointing fingers, just sharing information that his readers might enjoy or find useful.
