As a consumer of many public domain books on the Kindle, I find Amazon's policy good, except when they let the publishers of the paid versions game them.
For example, the "Adventures of Sherlock Holmes" (http://www.amazon.com/Adventures-Sherlock-Holmes-ebook/dp/B0...) is a public domain book, but their free public domain version has been "under review" for months, while paid versions continue to be sold for 99 cents and up.
This is pretty crappy behavior, IMHO. I know they don't make any money from PD books, but there are a lot of Kindle owners that enjoy PD books, and scammy tactics like this detracts from their reputation.
