Why did many churchmen object to the ottonian system of church control that continued under the salians

The churchmen objected to the Ottonian system of church control that continued under the Salians because they thought the church should be independent and self-governing. The Ottonian system for managing the church extended to investing bishops and abbots with their offices, controlling the church (lands of a church belonging to a secular lord appointed by the king), and appointing secular officers to church lands.
