As long as The Internet is available to Russians, people will find a way around Roskomnadzor blocks. All it takes is a single 100Mb VPS to provide VPN connection for 10-20 people. It's decentralized and can't be blocked, at least without making it criminal offense which did not happen yet.

But West, blocking Visa essentially made it impossible for average Russian IT guy to pay for VPS. And if The Internet would be cut off, the game is over, the entire country will be brain washed by Russian propaganda exclusively. I guess, it should be possible to use UnionPay to buy VPS in Turkey or something like that.

I, personally, don't believe that western propaganda is one bit better that Russian propaganda. It's the same half-truths, half-lies, just picked differently. But what I do believe is that every person must have access to all points of view, without any exclusions. And must be encouraged to learn all points of view for important subjects.
