The replacement of KF8 with KCR in Kindle for Mac is probably due to new requirements from Apple, especially since the same change was not made to Kindle for PC.

The change from .kinf2011 to .kinf2018 and the new DRM for KFX format were both likely done specifically to prevent DRM removal, in my opinion.

Added: it does seem odd to me that Amazon still has not done anything to prevent exfiltration of books obtained using the Download & Transfer via USB function of their website for owners of e-ink Kindle devices. It is strange that they continue to leave that open while closing other loopholes.
