I think it’s a lot more complicated than your oversimplification. For example, where does a quid-pro-quo relationship fit into your categories?

Saying leaked out of “ego” is equivalent to saying it was leaked “because”. We know it was something internal to the leaker’s psyche, but research should help us understand what led up to that point and how it could have been avoided.

For example, would you say a gossiper gossips because of “ego”?

A gossiper gossips to raise their status; having inside information (and revealing it) shows that they are more knowledgable than the person they gossip to.
