there is nothing stopping them from doing the same bullshit with firmware updates to the kobos and drm updates to the store and apps.

I never connect the Libra to any network, how can they do anything? I did actually install some updates since there were a few annoying bugs, but I just downloaded the firmware on the pc from https://pgaskin.net/KoboStuff/kobofirmware.html and updated it offline. Now all those bugs seem fixed and poor Kobo still hasn't seen the interwebs
