This is largely because it was specifically designed to be readable on low resolution screens without sub-pixel rendering (which wasn't a thing at the time as on a great many Windows machines you could only really rely on the standard 16 colour palette). It is also part of why other fonts with similar target aesthetics look much better in print and on more modern devices - techniques used to improve it for low resolution use have a detrimental effect when not using it that way.

The second is inappropriate use. It is still the better choice for child-hand-like writing if you are targeting 4-or-8-bit/pixel displays at 640*480 resolution (or not much more) on ~14 inch devices, but how many times is it actually used that way?
