The public released stuff was the distraction, the disinformation for media dissemination to the gullible and ignorant public. That took the spot light off the serious and unprecedented damage he did by staling Military and Intelligence gather methods and means both ELINT and HUMIT.
He did not “release” anything - he stole it. What was released see above was for the media. The US Government could not comment in detail lest they add to the damage.
By saying “He didn’t do anything important,” you are going up the wrong tree, which was what you were supposed to believe.
Everything he did was important both in the disinformation spread by the MSN and the theft of Methods and Means. Nothing in the Intel world is straight forward which is why it is confusing to people who never work in that field.
We're talking about the very same US Government and intel community that is this very day hip-deep in a coup attempt against our duly-elected President, aren't we?
I struggle to have sympathy for seditionists.
