Well this is just sad propaganda. Zelensky (and others) had publicly admitted to sabotaging deescalation agreements.
You don't want to fall for "nothing happened in Donbas before 22" bs.
It is really such a weird situation. Western and Ukrainian politicians had publicly stated they were actually going for a fight for a long time, but we still see people doing wired moral posturing.
Most news outlets in Russia nowadays aren't even registered as proper media, so they couldn't care less for any "propaganda filters".
The article tries to assert that there is a huge difference between a perception of a "military operation" and a "war", but in Russian "military" and "war" is the same word (the same word root): "военная", "война" -- so everyone is just calling it "war".
As an example, take look at this article (vc is a massively popular news/blogs site): https://vc.ru/finance/371584-glavnoe-v-ekonomike-na-fone-voy... -- use google translate to see what words are used and what people have to say in the comment section.
I would actually argue that Russians have much more sources of information available: Russian, Ukraininan, Western, independent. The evident post-truth politics from all sides breeds radical skepticism. The current situation is far from what can be called "a bubble", probably even further from what is happening in the rest of the world.
> They don't have media that talks about the war their country started
Stop spreading misinformation, this is not true.
This is basically the only thing that all russian-speaking media outlets are talking about. Plus, there is nothing preventing one from opening reddit and seeing what the western media has to say.
On the other hand, people in the West seem to be completely (and willingly!) disconnected from the situation in ru-net.
