"or threat to public interest"
It doesn't have to be illegal.
At what point does he cease being a whistle blower?
Still better than a full dump à la WkiLeaks, but the big question is whether the journalists have the OpSec skills to avoid leaking the documents to other governments.
It doesn't matter if it was directly or through an intermediary, everything that Snowden gave to journalists, Snowden leaked to the public.
Why not just leak documents related to that one issue? If he had, I would not hesitate in the least to call him a whistle blower, and in fact I think he'd be living as a free man right now if that were the case.
Second, we don't know the number of potential documents, nor how they may have been divided among those to whom they were disseminated.
Addressing the first point, it should take work and review, on an ongoing basis, to re-affirm the classification of that material. By default there should be a /reasonable/ and /short/ expiration time. If it costs too much to keep those secrets than that in and of it's self is a reason for not HAVING so many secrets to keep!
The cost, otherwise, is to our freedoms; to the very liberty for which our government is supposed to be protecting.
Perhaps you believe in your country right or wrong, but many don't nowadays, many feel little allegiance to national boundaries or national agencies which actively undermine our society.
What I find most interesting here is that this attempt by security agencies to collect it all actually means that their operation can be compromised by the smallest cogs in their machine whom they foolishly gave full access to. You can be absolutely sure that if Snowden walked out with this data, Chinese, Russian and other spies have the whole trove as well dating back years, because their security around private contractors was awful - GCHQ shared all this with the US without restraint, and of course all their data is now open to the world. So the ambition to collect it all and the entire collection of data (including data on western judges, politicans etc etc) is actually highly damaging to national security, even if you believe that flimsy excuse.
At some point if you're exposed to all this you might feel you have to take sides with humanity and take a stand, before these tools are used for widespread repression. At that point you start being a whistleblower, and your life will probably be destroyed by the powers that be (as his has been, or as Binney's was), because they now have that power.

I think the biggest lesson from Snowden is not technical, but the simple argument that the power of state and citizen must be in balance for society to function, and we must constantly guard against the state aggrandising power, because that is in its nature.
It doesn't: there are multiple different programs for reporting perceived illegal activity. Snowden never availed himself of any of these, but instead committed espionage.
These programs had been used by multiple people before, with no results. They are for show, so that people like you can point to them to show that there's "oversight".
Whistleblowing of the type done by Snowden is a last resort when there is no other option. The options you speak of are not credible avenues for change.
> One of the things that has not been widely reported by journalists is that whistle-blower protection laws in the US do not protect contractors in the national security arena. There are so many holes in the laws, the protections they afford are so weak, and the processes for reporting they provide are so ineffective that they appear to be intended to discourage reporting of even the clearest wrongdoing. If I had revealed what I knew about these unconstitutional but classified programs to Congress, they could have charged me with a felony. One only need to look at the case of Thomas Drake to see how the government doesn't have a good history of handling legitimate reports of wrongdoing within the system.
> Despite this, and despite the fact that I could not legally go to the official channels that direct NSA employees have available to them, I still made tremendous efforts to report these programs to co-workers, supervisors, and anyone with the proper clearance who would listen. The reactions of those I told about the scale of the constitutional violations ranged from deeply concerned to appalled, but no one was willing to risk their jobs, families, and possibly even freedom to go through what Drake did.

Every time I've been a contractor[1], I've been treated likewise.
[1]never been contracted out to a government agency of any level.
Government activity that is fascistic is usually going to be completely legal or made legal once revealed. We saw the government do this with the USA Freedom Act. Before that, they claimed to have authorization under the FISA and PATRIOT Acts. They do not want oversight, and the "abuses" are actually functioning exactly as intended. This is also why they endlessly lie to our faces about what is going on and don't get fired, even when they have been outed repeatedly.
Also, there's the documented fact [0][1] that whistleblowers at the NSA who go through the "proper channels" ultimately gets you fired, ostracized, raided, and prosecuted. So really, it's a non-starter to claim that they should have reported illegal activity.
