Snowden seems to have revealed secrets that a huge number of people had access to (over a million?)
Snowden was a contract sysadmin for NSA. Surely there aren't anywhere near a million such people? Where are you getting that number from? Are you talking about the 4 million people having “top secret” security clearance? I'm pretty sure the vast majority of them did not have access to the particular secrets that Snowden is revealing, i.e., there are other controls besides the clearance level that prevented them from accessing those secrets.

Yes, "knowledgeable people" are saying that Snowden has damaged U.S. security.
I'm currently working on a research project for MIRI, and I would welcome feedback on my research as I proceed. In this post, I describe the project.
As a part of an effort to steel-man objections to MIRI's mission, MIRI Executive Director Luke Muehlhauser has asked me to develop the following objection:
