I now recall the name of the other mainstream publisher Alana. Christian publisher Thomas Nelson. They now have a self publishing arm West Bow Press.

Only when new authors have spent thousands of dollars on their book only to sell a few dozen copies (the majority of self published books fail to sell 100 copies) and make a massive loss will they realize what a scam this is.

In case you're wondering who anonymous is it's Paul Green for Encyclopedia of Weird Westerns. :)
