There are a lot of countries they have never published anything on. They have a smaller number of large leaks, so that is not necessarily out of the ordinary.
I think it is credible that Wikileaks were provided some documents from Russian state-sanctioned actors, who knew Wikileaks would publish them, and that the state-sanctioned actors did so to serve Russian interests. But the claim that Wikileaks as a whole is biased towards Russia doesn't seem likely.
Things?
Correct me if I'm wrong but you're linking to 1 single publication. It doesn't seem they have anything else about Russia. From a quick glance a it, it reveals that Russia have infrastructure to control and monitor who in Russia is accessing what over the internet. Looks like a rather weak, insignificant leak to me. Which is what I was saying to begin with.
