Devices should be supported longer than 14 years. There is nothing about a 1st gen kindle that makes it incompatible with modern technology. For Amazon, an immortal entity, to act like 14 years is already gracious is nonsense. A 20 year lifespan (including repairs) should be the bare minimum standard.

Cutting them off from the online store is one thing, but the fact that they are bricked if you deregister or factory reset them is awful

I have a kindle keyboard that hasn't been online in over a decade, but still gets regular use. i upload drm-free ebooks i own using Calibre. Now it will be impossible for me to give it away since it is forever zombie locked to my Amazon account
