Russia is a barely middle income country with a shrinking GDP, a shrinking population and an ageing military.
Surprising that I've never heard a single story of Russian influence in my country, India. Apparently, Putin and his stooges were able to infiltrate all levels of politics and media in the rich western world, but don't give two hoots about its more direct economic rivals in the BRICS.
And while you're correct about your overall assessment of Russia, that is precisely why it has to resort to measures like these. It cannot compete militarily, and it cannot compete economically, so it is left to resort to Machiavellian devices to fight for (what it believes to be) its rightful place, if not on the top of the pile, then at least on the top tier of it. That's what really grates so many people in Russia, both elites and commoners - that it was a superpower, but it isn't anymore. A lot of people really, really want it to be one again. And for them, the definition of superpower is, "they fear us".
You know, like happened with the utterly corrupt British government, right before Brexit ..
Similarly, when civil and security services and the executive quite openly distrust each other and brief against each other, "it could all be explained by paedophilia" is just unnecessary sub-4chan speculation.
