In regards of profitable, I hope you also consider internal cloud computing usage as it were used by an external party.
E.g. if stuff like AlphaGo, Youtube, or the Search Engine used tons of cloud computing resources you should not count it as no profit made (actually loss because of power consumption, server housing, networking, ...), regardless if those cloud resources were anyways unused. Then it's up to your colleagues then to make the profit.
In my opinion the major issue is, that most people don't understand what is happening.
