In a big picture, it's not just russian politicians who tight control over the free internet. The main problem in russia is not just politicians, it's a vast majority of russian people who voted for Putin and his party and totally support current regime.
May be for western people it's hard to believe how can it be possible to support this crazy regime. I can tell you that even top managers from leading russian internet company (from my private conversation with them) dreamed about great russian firewall because in that case, they won't have competitors like Google. Furthermore even IT guys like Putin regime and don't get worry about crazy laws passed against the internet. I assure you in that because many of my colleagues really like Stalin and really like what's happening in Ukraine. Almost all people in Russia really hate western world. They don't care about currency exchange rates and inflation, they care only about imperialism. When Putin made desision about Crimea, and when people totally supported it, I stopped believe in Russia at all.
Russia is a pure soviet country, with pure 100% soviet mindset, vast majority of russian people like idea of self-isolation. This is why Russia has no future as a liberal market-driven country.
And this is why I'm actively looking for a job abroad.
