@peacefulpete - You say you understand the Russian position, but as far as I can see it from your following explanation - it's definitely not the case, unfortunately.
The reality is that the current Russian gov't doesn't give a damn about the things mentioned as a reason behind the ban on Jdubs. Even more, those things are exactly what the gov't itself does on a regular basis: 'propaganda of exclusivity, superiority', (and similar stuff like terrorism/extremism, hate speech, war propaganda, nationalism. etc).
One could argue about the actual reasons Russians love to ban Jdubs, but it's 100% not because of their care about welfare of the citizens, or 'fighting extremism' (this very last thing just sounds ridiculous in the mouth of KGB fellows).
