I don't think they will. I have all the information on this topic you can get but it doesn't matter since I can't do anything about it. At best I will not achieve anything, at worst I will get imprisoned and tortured, so what's the point in trying?
You seem to have a very benign definition of "worst". At worst, they are going to see their country collapse, a repeat of 1917, then misery and/or death of all people important to them.
Because that's what people have in mind when you friendishly suggest them to 'topple' their government.
You are correct if we're talking about somehow taking collective action, but I was talking from the perspective of a single person without a group they know well enough to start a revolution with. I think most people in Russia fit that description, at least all of the ones I know do.
