Hello, from books ive been reading they seem to describe anti-squat as a good thing which makes sense in my mind as it "pushes" the rear tyres into the road against the cars weight.
The theory is the other direction - it creates a force that uses traction from the tires to push on the sprung mass to cause it to pitch less under braking or acceleration. It is the same concept as jacking forces created by roll centers just rotated 90 degrees.
It is often used to control the tire contact patch and dynamic camber by minimizing movement of the sprung mass without using heavier springs. An independent suspension would see more camber change as you brake or accelerate without it - how much depends on a bunch of things like CG height and spring rates so the answer isn't a clear cut good or bad.
