Maybe Europe isn't perfect, but the Russian morals are so low that no effort is requried to be better than them.
"You can't ask these questions, or we'll all go to jail."
Actually, the range of methods is slightly wider. E.g. there was a French politician investigating the сase of corruption of Ursula von der Leyen. That politician died from "heart attack" just a few days before the hearing. Ah, that's a "conspiracy theory" and "conspiracy theories" are explicitly forbidden now in several EU countries. Also, very convenient.
Same for comments in the Internet. E.g. if you writing something western people doesn't like on Reddit/Facebook/whatever, the only reaction you'll get will be "you're a Kremlin troll"
No need to think and analyze yourself. There's only one truth in the world and it comes from Bloomberg/CNN/BBC.
