bitmap fonts were the norm on computers for many years, and are still the default if you are running a computer in text mode (ie not running X11 or Wayland on linux / BSD), or using basically any low powered device with a screen. I was surprised to hear that anyone had trouble reading these, since they were just what fonts looked like on screens with certain constraints. I can understand that some people have become so used to high DPI displays and antialiased truetype fonts that they consider fonts with visible pixels ugly. If anything I would expect them to be easier to read with poor vision, since there is not much subtlty to miss out on.
