There are a large number of highly active Ukrainian channels on Telegram, all about as anti-Russian as you would expect. There are Ukrainian government ministers operating channels on Telegram. How does that occur on a "Russian controlled medium?"
I don't speak either Russian or Ukrainian. I know none of these channel operators. Yet I've been granted approval on a number of "private" Ukrainian channels. Certainly a Russian could as well. Why wouldn't Russia's state actors, given that they enjoy "control" of the medium, shut it all down?
