Saw an advert for this thing, in theory it looks pretty good (repairable e-ink tablet) but I’m a little confused by their statement that it will at some point in the future run a linux based operatint system

“A Linux-based system will be open in the future for community modifications and customizations. *Not built-in with the device”

I guess this probably means it’s not actually as open as they claim if you can’t just put mainline Linux/android on it but thought I’d ask here cause in theory it seems like a neat tablet
