How did the Space Telescope Mirror End Up Flawed

This is very much not how I remember it being reported around the time of the repair mission. I'm sure that at the time it was incorrectly reported as being due to the effect of grinding the mirror under earth gravity.

YouTube description:

The Hubble space telescope was at the time meant to be the finest telescope ever made with the smoothest most perfect mirror on earth.
So how did the $1.5 Billion project end up with a flawed mirror that had a grinding error 10x greater than the required tolerance and so bad that it could not be focused once in space.
