I remember reading a study that posited low status men tended toward misogyny when they felt threatened by the skill of women they were competing against, and this was the first thing that came to mind as I was reading over this whole saga.
Most of the comments here reference the fact that her skill is self evident. He could easily have felt threatened by her technical skill, and the fact he couldn’t plainly see it as other commenters did adds credence to his own deficit of technical ability.
The fact that he maintained a sustained slander campaign when he ostensibly had other priorities implies he felt that ‘exposing’ her became important to him, again a trait of insecure, low status individuals.
