That would be a first! Wonder what exactly pushes their buttons. Perhaps just that it's a surrogate? Wouldn't surprise me.
Giving the Bank of Russia censorship rights regarding alternatives is pretty pushy, but, soon, "in Russia legal tender is only tender". Shame for them they won't be able to actually prevent Bitcoin use, and soon only criminals will use Bitcoin.
Might have a bad ripple effect on Bitcoin in the rest of the world. We'll see the price jump up soon.
