The one thing you didn't touch upon, in addition to these intellectual property questions, is classified information.
It is a truism to invoke classified information as a factor in anything involving the NSA. However, his 'unfair merket advantage' through access to classified information is a valid addition to your argument because the discussed techniques are specifically about behavioral modelling of threats whose very identities can be classified, as well as the intelligence methods used to observe and learn about these methods.
I doubt anyone is going to challenge a former NSA Director on the improper release or proliferation of nationally sensitive data. The release of such information by 'fiat' can even be beneficial if it really and truly does protect our financial institutions. However, I would be concerned about a noticeable trend to allow high level officials to monetize their access to information.
