Belta (the state news agency) was using YouTube for propaganda for almost a year since the protests in 2020 in Belarus. Videos of "confessions" by beaten protestors were very common. I'm not sure how much the government spends on ads but you can hardly watch anything on YouTube without stumbling into a propaganda video.
I've not seen Western states using videos of tortured hostages to signal boost their propaganda channels. I think this is a significant difference, don't you think?
I mostly share your view on this, but don't forget that when our TV stations show on repeat how our cops are beating Antifa members in demonstrations, that this has also the same chilling effect on us. They are usually followed by interviews from higher-ups in the police force who then frame their view of things. Also, you don't see them followed by interviews from Antifa members, which might have something just as valid to say.
It is a different thing, but there are similarities.
It's not allowed in the States either, but it still happens. It happens in the EU too. In general, the Western countries are not free from blame when it comes to war crimes due to complicity with the US :/
