But, at least in Russia, they don't and they won't because that's not how power transfers work in this country.

Alexei Navalny was the last person attempting to change this, but he failed.

Also Russia has its own social media, search engine etc., so some information simply doesn't reach the common Russian.

Over here in eastern Europe as far back as in the 00s there was the concept of "Russian internet"(Runet) - it wasn't technically sealed off from the rest of the world, but was more a small, independent world in and of itself that exchanged information mostly internally, in Russian.

Navalny is a nationalist, Russia is multi ethnic country and it's always been clear that he wouldn't gain any power there even if Putin is removed and he is released. Navalny team is also falsely presenting themselves as friendly to Ukraine while trying to get their government to give better equipment to Russian soldiers so that they can kill more Ukrainians.

Roskomnadzor tries to control RUnet (Russian language websites) even in some former Soviet States.
