Amazon has taken no steps to hide this information.

I have intentionally stayed away from examining the details of encrypted KFX files. As can be seen in the first post in this thread, even "Simultaneous Device Usage: Unlimited" books contain strings like "amzn1.drm-key.v1" and I don't see Amazon calling these books "DRM-Free" anywhere. I don't want to be put in a position of having to defend against an accusation of DMCA violation so I am going to avoid reverse engineering this aspect of KFX. (But I will be happy if someone else does so.)
Tor Books used to say in the description that the book was DRM free as requested by the publisher. I looked at a few books from Tor and that phrase is no longer in the description, but it is inside the book. If the book says inside that it is DRM free, I don't think it would be a DMCA violation.
