Adding preload doesn’t compress the spring, it extends the shock and increases ride height.For every inch you compress the spring you increase the resistance force. The more you compress the spring the more resistance force is applied. It's at the end of the travel you notice the spring change more than the beginning.
Linear springs do not change rate anywhere in their compression. They only change the resistive force.
