The father of a friend worked at a high position at Canon. For a specific enterprise command, the client company wanted printers with a lifetime 20,000 copies instead of the base 10,000. Canon went "no problem, we'll see with our engineers" and actually they only had to remove a small device which was basically a print counter and would artificially block the ink input at approx 10,000 copies. So nothing to do with good engineering, only bad business practices.
