Don't say DLP but Data Management
As data governance is a emerging discipline, the idea of storing data in the cloud triggers this discipline by default. Both business and risk management will state their wishes and requirements. Resulting in a set of policies and instructions enabling the business and reducing the risks inherent to data storage.
But business is "the" stakeholder in this question. As IT security and risk management we can make business aware of risks. Keep in mind, don't bite the hand that feeds you (yes they pay the bill)
A small mental image: a car needs brakes, not to slow down. A car needs brakes to go faster. (Thank you, Serge Moreno) As long we act in IT security and risk management as brakes without having a car (representing the business) we will be seen as a burden preventing business to move faster.
