I'm sorry, but it still doesn't make sense. I work at the executive level in risk management and information security. If I were to discover that sensitive, executive conversations were being leaked in my company I would find the source of the leak. There are only so many people who have access to that level of sensitive information - especially because it's coming from discussions in real-time, and it is not difficult to narrow it down as to who is leaking it. The person feeding you the information is either close to the discussions, or is in a position to have access to the information electronically. Either way, very easy to find out who it is.
Given that the information you are providing seems to be plausible and since you have been right before, it sounds to me that these leaks are purposeful, or the information being leaked is not as sensitive as we think. I agree with a previous poster that news outlets are not reporting on it because it cannot be verified. But as sure as the sun will rise, the person supposedly leaking this information would have been caught if the companies wanted him to be.
