I'm "glossing over it" because you are, I explicitly asked you in another thread what he leaked that wasn't relevant for the public interest.
I'm not sure what your angle is, but the NSA proved that they were beyond contempt when they lied to the Senate and there were people in the room that knew the situation who didn't pull them up on it.
Regarding Binney specifically; the IG's report largely supported his claims, but it was classified and changed little. Thomas Drake, a serving NSA official who raised similar concerns internally, also got nowhere.
The government's serious attention came only after the New York Times revealed warrantless wiretapping in December 2005, and it came as a leak investigation. In 2007 the FBI raided the homes of Binney, Wiebe, Loomis and Roark; Binney has said agents drew guns on him while he was in the shower.
Drake was indicted under the Espionage Act in 2010. The case collapsed in 2011, he pleaded guilty to a minor misdemeanour, and the judge sharply criticised the prosecution's conduct. So the substance of Binney's warnings was mostly ignored or denied.
Binney went fully public around 2012, and NSA officials publicly denied that they kept files on ordinary Americans.
The core contrast is that Binney went through proper channels, took no documents and was not believed. He was investigated anyway and achieved almost no reform. Snowden bypassed every channel, took vast amounts of classified material and was pursued far more aggressively, but he forced a public debate and concrete legal changes.
You can pretend that's not true, but you'd be ignoring reality.
