Respect to Blazie Technologies, they are at least trying

So this BrailleNote Touch topic made me think again about cost of device vs what we get, hardware and software wise.

At least, they are trying, this is made for power users, and now with the rpi compute module 5 and 16gb ram, it's probably the most advanced in term of raw compute power in a blind assistive tech we've ever seen. Run on linux with full access if we want.
I wonder if their devs can contribue to the linux accessibility stack directly?
I'd love to see something like bt-speak software but inside canute console, something in the latter is opensource so maybe.
