Hmm... It's the publishers not Amazon? Who else besides Amazon is using Topaz?
Why do they have their own Format AND their own DRM? Why are they trying to
lock down certain authors, with exclusive contracts? Their whole approach to ebooks
and their own eReading device has been to limit/constrain the consumer, ala Apple.
Why is there not a common format and DRM employed by the publisher, that you would
see at all the retailers, if it is the publisher who insist on DRM?
