this is very disingenuous. it's a product being developed by a company. this isn't some github repo with a few images of an open source e-ink reader made by some hacker guy, this is a proper thing that is being designed, developed and maybe pushed to the market.
and to me, if you're a company developing a product you should at least make sure its basic existence is justified. nobody has yet told me why this product has any real use.
I couldn't care less about the market. I am personally not in the slightest convinced by this product and I specifically asked other people to please tell me why they would want it. I just really dislike bullshit products (not projects) that lead nowhere and brain drain the open source world.
I read pdfs on my laptop, code using gedit without any fancy plugins for code highlighting or whatever and drop to the terminal if I need to mess with stuff. Hell, the majority of the time surfing the interwebs is in reader view on my iPhone, like a good 90% of the time.
Plus, you are in no way entitled to the brain power of anyone who you are not directly compensating for their labor.
Maybe nobody owes you an answer?
