Isn't the thesis of the post that that exact discrepancy is due to insufficient communication between the people at different levels of the stack?

An abstraction is an interface between two levels of the stack, right? I think the thesis of the post is that the exact discrepancy you describe, between the abstraction's actual behavior and the desires and expectations of the people one level up, is due to insufficient communication between the people one level up and the people implementing the abstraction's actual behavior, which due to Conway's Law are separate groups of people.

You mention "information leakage", but that's leakage between software components at different levels of the stack; perhaps you have that confused with the "insufficient communication" referred to by the post, which is between groups of people at different levels of the stack?
