Pitching is absurdly complex.
There is absurd amount of confusion about pitching, but pitching isn't complex. (Heck, if @BoardMember can figure it out, anyone can. )
I would teach anyone on my rec teams who wanted how to pitch. Any average girl can be taught to pitch "good enough" to put the ball over the plate and have fun doing it.
Were they throwing the ball 60MPH? Nope. Did they have 10 pitches? No. Could they pitch 14U-Gold? No. Could they "just throw strikes"? Yes.
The problem is that there are way too many people espousing crazy theories.
