Wikipedia is not currently banned in Russia.

But the Russian branch of Wikimedia as an organization is.

Also, pretty much nobody in Russia uses Ruwiki, everyone keeps using Wikipedia.

That’s all not to say it isn’t a troubling development, though. But Russians are more likely to access Wikipedia through VPN than to rely on Ruwiki. The game’s not lost.
