Any significant Russian leak will be instantly picked up by the western media.
There is a lot of leaks on Russia in the media. No one actually cares anymore since it's mostly corruption stories and everyone is already knows there is a lot of corruption there.
Here is the last corruption story on prime minister Medvedev: https://navalny.com/p/5255/
A better question: Is this story (obviously in Russian) an example of independent media in Russia? I thought that was a dangerous business to be in?
Also, are there ever leaks on the scale of Snowden? I'd say the lack of a Snowden level incident isn't damning as that's a high bar for sure. Jesus. That dude put it all on the line.
It is dangerous. This guy's (Alexey Navalny) brother is in jail on a fabricated lawsuit as a hostage. Alexey himself was also convicted guilty and the only reason he personally is not in jail is because he will only get more rating points from being a political prisoner.
There was a massive smear campaign against him on all major government controlled mass media where they were blaming him to be an US agent and also a corrupt person.
The only reason Putin has good approval rating now is because he managed to convince the majority of TV owners in US conspiracy.
And Ukraine crisis, sanctions, ISIS, and oil price drop did actually convince majority of Russians in that.
So as long as people blame US Putin is safe.
One similar thing I see here in US: when facts are too painful and too obvious - blame another country.
