Anyone else get this email from Amazon about using Calibre?

I got this email from Amazon with a title of "Alert from Amazon DTP". It seems like little more than a dirty business type letter trying to get me to use something other than Calibre to produce self-published books for the Kindle store.

Hello,

Thank you for publishing your titles on the Kindle Store through Amazon DTP. During a review of your titles, we noticed that you used Calibre to create Mobi books. Please note that if you use Calibre to create Mobi books, they may not be supported if we add features to the Mobi format. Therefore, we suggest that you use applications like KindleGen or Mobipocket Creator instead.

KindleGen is a command-line tool used to build eBooks. This tool is best for publishers and individuals who are familiar with HTML and want to convert their HTML, XHTML, XML (OPF/IDPF format), or ePub source into a Kindle Book. Please click the following link to download this application along with the User Instructions:

You can also find more information and instructions for using the KindleGen in our Kindle Publishing Guidelines document. Please click the below link to download the same:

However, if you would want an application with an active User Interface, you can use Mobipocket Creator. The Mobipocket Creator allows publishers to create ebooks with an easy-to-use content authoring tool. This software also includes Adobe PDF, Microsoft Word & Text File Import wizards. You would also be able to design an active Table of Contents and a personalized cover image for your titles.

Please click on the link below to download the Mobipocket Creator application:

Please note, KindleGen does not support DRM. If you want to apply DRM to your books, you can do that through the DTP web site.

If you have any questions, please feel free to write to us at dtp-support@amazon.com.

Thank you.

I will continue to use Calibre.

poor Amazon. They see the walls on their walled garden crumbling. So they resort to FUD, standard corporate tactic.

Thanks for sharing.

I think this is a case of Amazon getting fed up with Calibre running rings around its own tools. Some of its ePub to MOBI conversions are pathetic.

If Amazon does extend the MOBI format for the Kindle, are they really going to release a new version of MobiPocket Creator (last updated two years ago)? In any case, I'm sure that Calibre will be able to track the changes if this does ever happen.
