Both my Kindle Touch and my Kindle Paperwhite gen1 are still completely fine. And I havent noticed any typesetting etc that doesnt work.

All of these discontinued devices support the AWZ4-format (which can be de-drmed and what im guessing this whole thing is about), but the newer ones use KFX which locks you perfectly into the Amazon and Kindle-ecosystem

It’s more difficult, but KFX drm is still possible to break.
