> I know that people can joke about the west in Russia but are people allowed to make jokes about their own government in Russia and in the associated eastern european states?

That's a tough question. For example, when I was active in TikTok (I grew tired of it pretty fast), I've made a lot of very critical videos that had a lot of views. In one of them, that got almost 100k views, I explicitly said that Putin and his gang are usurping power, and while the current Russian laws say that it's punishable up to 20 years in prison, I think that they deserve the death penalty. I did not get in any trouble for that. But many others from Russian Libertarian Party (which I'm a member of) have, even though they've said much less. May be they had a wider reach, or may be it's just random, I don't know. And I wouldn't be surprised if a couple of years later I'll get 5 years of prison for these TikToks.
