What good is free software when manufacturers can just require the firmware to be signed, thereby disallowing any and all modifications? We'll never be truly free until we can manufacture this hardware at home, just like we can make our own software at home.
Admittedly I haven't done anything myself, though I admire those who have.
when I saw the headline for this article I first read it as "Canon sued for disabling scammer when printers run out of ink" :)
