Snowden referred to the Russian authorities’ attempts to control its citizens on the Internet by imposing restrictions as ‘fundamentally wrong’.

“I've been quite critical of (these policies) in the past and I'll continue to be in the future, because this drive that we see in the Russian government to control more and more the internet, to control more and more what people are seeing, even parts of personal lives, deciding what is the appropriate or inappropriate way for people to express their love for one another...(is) fundamentally wrong," he said.

In June 2003, Snowden handed over evidence of the US and UK secret services spying on people on the Internet to the Washington Post and Guardian newspapers.

As a result, he had to leave the US and fly to Hong-Kong and then to Moscow where he was granted asylum in August 2014.

In the US, Snowden was charged in absentia with espionage and theft of government’s property. Under the US laws, he is facing a lengthy prison term of up to 30 years or death sentence.
