@BryanLunduke Lets talk about printers. I got one and when the ink got over, tried to manually refill it. But the printer won't use the newly added ink and print everything green. It seems like the printer manufacturer wants me to buy new (very expensive) cartridges which I think is against my freedom to use my device as I want. What do you think about this? Also, what do you think would Richard Stallman do about it.
