In a recent communication, Amazon has alerted Kindle users about significant changes set to take effect from next month. The notification pertains to the phasing out of support for sending MOBI (.mobi, .azw, .prc) files through the “Send to Kindle” feature, starting November 1, 2023. This change, as News18 pointed out, specifically impacts users attempting to send MOBI files via email and Kindle apps on iOS, Android, Windows, and Mac.
Epub doesn’t natively have user tracking and DRM either. Mobi files are just ancient and there are better alternatives for them. Like bmp files vs jpg.
Epub is actually pretty good. And it’s been supported for a long time now. Hard agree.
