I know all of that. I'm a native Russian speaker and I have quite a lot of Russian friends, I'm pretty well aware of the situation. Nevertheless, despite all the government’s efforts and the enormous amount of money invested in this, there are still - at least for now - ways to bypass the blocks even there. I suspect that as long as they don’t physically cut the cables, there will always be ways to circumvent censorship. And yes, I’m not talking about carrier pigeons :)
So I hope that in the UK and other European countries, by drawing on Russia’s existing experience, people will be able to adapt to these restrictions before they become too severe. Of course, the government could also adopt Russia’s approach right away, but that’s unlikely, as it would provoke far too much resistance from citizens - they aren’t used to that level of restriction. If Europe does indeed continue moving in this direction, everything will happen gradually, just as it did in Russia; no one will roast a frog with a flamethrower - they’ll cook it according to the classic recipe, so to speak.
