There have been several threads about this on HN over the past few days and months. Just to avoid the confusion that seems to follow these, a few notes:
(1) This is the “Download and Transfer” option where Amazon allowed users to select books they had purchased a license to and download them from the Amazon website.
(2) The ability to transfer books from your computer to your Kindle using a USB cable is not affected.
(3) The ability to send non-Amazon-licensed ePubs using the Send to Kindle email feature is not affected.
