That Amazon decision

There are lots of posts, comments and discussion everywhere about Amazon's recent decision only to sell print-on-demand books if the printer used is Amazon's own Booksurge. Perhaps the best analysis I've read so far is this one on O'Reilly Radar, a post which has the added benefit of, at the end, a set of links to other coverage at Publishers Weekly, Library Thing, Booksquare et al. Whatever one might think of the business decision, it seems to signal the end of Amazon as a collaborative network of partners (buyers as well as sellers), and the start of Amazon as a traditional business, competing with publishers and competing for readers. As a consumer, I preferred the old "we can join them we don't need to beat them" approach. Now I have to go to more sites to find what's available and hence I want, instead of being able to compare everything on Amazon. (Maybe everything wasn't in fact on Amazon before, but I thought it pretty much was, apart from the odd obscure out-of-print book. That "user faith" is something the site has now lost, in my mind.)
