Intelligence was always this leaky, there just wasn't social media and modern-day yellow journalism to twist it and spread it around. And we didn't have outrage culture, which provides a very blunt and dangerous mechanism for leakers to leverage.

The only real secret intelligence is tactical (military or otherwise), because we aren't quite that craven, exceptions notwithstanding. Everything else is intrinsically political and has a very short half-life as a secret. Work for a few years inside the Beltway, especially with or near people who are connected (e.g. lobbyists, think tank scholars, appointees, Pentagon staffers, international orgs, etc), and this becomes obvious immediately. Secrets are social currency more important than money and maybe even title. Everybody shares secrets, albeit usually in an obnoxious, obfuscated, pretentious way; even the interns.

As the other poster notes, selective intelligence leaking has been going on forever. And if there is a lack of Ex-Bush intelligence community members in the press, it is because the whole torture thing made then step away from the public eye.
