Dvd players didn't need to know the date. The new world of constantly evolving drm schemes falls into this world, making it east to eol devices if not updated

"The move will mean owners of older Kindles, including its earliest models such as the Kindle Touch and some Kindle Fire tablets, will be unable to download new e-books."
For a more tech-oriented site, according to Ars Technica Amazon removed the ability to upload over USB:

"Previously, owners of old Kindles could have worked around this loss of functionality by downloading books locally and transferring them via USB. But Amazon removed the ability to download books to a PC or Mac in February of 2025."
I don't like to brag "I told you so" but I saw this coming 16 years ago:
Amazon removed the ability to download files from them to your computer. And they will soon be removing the ability to download files from them directly to older kindle devices. You can still download a MOBI or EPUB from anywhere else online (though I think some older kindles don't support EPUB) and transfer it via USB, and will still be able to after they EOL those older devices.
But you cannot just USB an EPUB onto your Kindle without any conversion process. (Calibre does make it very simple, though.)
I'm assuming send to kindle will no longer be supported on these older devices.
The big problem is that Amazon no longer allows you to download books from their site to your desktop, so you have no way to actually get a purchased book and send it to the kindle even over USB. However, if you buy non-DRM books from other book sellers you won't have this problem.
As evidence, note that instructions for rooting them requires the device to be registered - this is because it won't be accessible over USB until you do so: https://kindlemodding.org/jailbreaking/WinterBreak/
So if you can't log in...
I've bought a number of books on Kindle that were explicitly marked as being sold without DRM. Does this mean I've lost access to any DRM-free downloads that I haven't already backed up?
Download and back them up now. Or just pirate them if you need them later.
The entire Kindle store system will cease working on older Kindles after the cutoff. Still works as a reader, but expect to lose things like location sync across devices.
I don't buy from Amazon, I don't turn on WiFi on my Kindle because it eats battery life, I always travel with a laptop, and I only use it to read outdoors. So I really don't care. It's my beach book. At home, I'd rather read on my iPad.
Oh, and FWIW, you can install Tailscale to a jailbroken Kindle and Taildrop files to it over WiFi, if it can read the format (for the old ones being discussed, that's mobi or azw3).
