Sounds like a lot of Russian people are speaking out now, especially famous ones. Whether it will have any effect or put pressure on Putin remains to be seen but the message is getting louder
Dont make the mistake of judging these kinds of countries by the same standards as ours.
You need to check the motivations of the FSB, the courts, the political system.
Not some randoms on the streets/internet, who get arrested and thrown in jail for 5 years 24 hours after they protest
Read about Navalny - the poor bugger is doing hard labour for 2 years, after Putin poisoned him with Novichok!
