I can create KFX ebook with Kindle Preview 3 without drm. Until the last version I was able to import ebook from Kindle PC app into Calibre and make them drm-free in KFX format (and only after that was drm-free I was converting it to epub).
So no, KFX is not drm by default as a format, is drm by default when you download any book from amazon right now.
Of course I don't like it since it is a proprietary format, but KFX and drm are two separate things. That's why KFX Input/Output exist.

I know KFX doesn't have to have DRM. What I'm saying is that Amazon adds DRM to KFX regardless of the fact that you don't want DRM. Because of the way the DRM works with KF8 (aka AZW3) Amazon decided to create a new file forat so they could also create a new DRM that they can update as needed to prevent removing the DRM.
KF8 has been cracked which is why Amazon created KFX instead of updating the KF8 software to do hyphenation, Kerning, and Ligatures. Adobe Digital Editions does all the enhanced typesetting that KFX does and it doesn't need some pre-compiled format to do that.Amazon could have just as easily done it with KF8. But because of the way KF8 DRM works and the fact that it's been cracked, Amazon didn't want to update KF8 and instead wanted to try to make it harder to remove the DRM and thus KFX (aka Devil's Spawn) was born.
