The feature of public corporations that was weakened by privatization is governmental control. Public corporations are usually owned by the government and are managed by appointed officials who oversee their operations. These officials are accountable to the government and are required to follow certain regulations and guidelines set by the government. However, when public corporations are privatized, they become privately owned and managed entities. As a result, the government loses direct control over their operations and management. Private owners and managers are not required to follow the same regulations and guidelines as the government officials, and they may prioritize their own interests over the public interest. Therefore, privatization weakens the government's ability to control the actions of public corporations, which can have negative consequences for the public.
