Right now, it's continued operation relies entirely on state secrecy laws. If Obama or some future president realizes that it is that one provision that is protecting illegal actions, he can promise to pardon anyone of the laws they have to break to expose those illegal actions.

One of the biggest problems with our whistleblowing laws is that if you have to break laws to make things right, you may be seen as righteous, but you'll still be prosecuted for the laws you had to break to accomplish that. We're still a nation of laws and the only laws that can overturn that is the constitutional power to pardon. The only crime the president cannot pardon is impeachment. Any individual that isn't in an impeachable position could expose wrongdoing if the president had their back.
