Not that I disagree with your take on alleged Free POD publishers, but there is one out there that seems to present some competition to all the wannabees out there; namely, WordClay.com. It would be interesting to see a comparison between them and others.
WordClay is owned by Author Solutions, the same outfit that owns AuthorHouse, Xlibris, iUniverse and Trafford. There are numerous complaints about the Author Solutions companies online.
WordClay appears to work the same as Lulu and CreateSpace. They lure authors in with the word “free”, and then upsell them on services authors can get for less elsewhere.
