That sounds like conspiracy thinking. The media isn't able to suppress the CIA's good deeds, and I don't believe they'd try. "Big alien invasion averted thanks to heroic CIA agent" is a great headline. So great in fact, that fiction books are written on that premise.
With all the minor and major leaks from the intelligence community, they're supposed to have a super tight and successful conspiracy going to hide the fact that they are actually effective? I have some doubts, both on the technical part (large conspiracies are hard) and the reasoning.
