I read the Russian language article linked above and it does say that one deputy in the Duma, Evgenij Fedorov, actually proposed such a miscreant law. Like Germany, Russia has never understood the idea of a free flow of information and opinion.
If this law is passed, and if others follow, Russia will eventually become irrelevant. Hopefully Putin will understand that this proposal is a trap and will steer clear.
Even so, the West does have ways of dragging it into line though. For example, if the Left and the Greens ease up on their phobia of fracking (some of it justified), Europe can produce its own oil and starve them. But no one wants that. Putin is losing popularity rapidly now that he has invaded Crimea so the Russians may take him out next election.
