It's just matter of time before they're all locked down, even the bad ones from 2020.
Just like android where basically it's all bootloader locked, except for a few suspiciously special models like the Pixel. Or a "new" 1000$ model with hardware from 2018.
Instead of pretending there isn't a problem because there are still option, you should realize the WINDOW IS CLOSING
A Raspberry Pi with an E-INK screen is surprisingly doable.
The raspberry pi has no low power modes / suspend states, to prevent it being used as a cell phone or tablet.
The standalone eink display are also very expensive, more than a entire eink reader and there is very little choice and they cannot be harvested from a working device.
Low power states is a good call,
Looks like there's a lot of work on using ESP32 for this kind of thing, even a couple open projects, but they end up bit-banging the screen into submission. not super elegant.
You can get 7" eink panels for $50.
