For christ sakes, as you state, there is a whole new generation that was born after 2000 in russia. 90s are out and there is control of information> it doesn't matter that they can learn about this topic from internet or hbo or stalker (yes, sure, all gamers will assume that game is based on real events). if they are not taught about it, they won't know.
did you see new history books in russia btw that were published a couple of weeks ago ? do you see the new versions of history been on tv ? the laws about spreading "false information about ussr in wwII" ?
Which hilariously enough is what they do when drafting and recruiting new soldiers...
The bulk of Russia's invasion force is comprised by people from remote villages.
You're talking about people who risked their lives, and many died, to pillage washing machines and indoor toilets.
Do you really think the literacy level and access to information from the average Russian grunt on the floor accommodates this info? Many didn't even knew where in the world they were stationed.
