You mean Ukrainian demographic?
Yes many went abroad, just as Romania, Ukraine also lost millions from the population mostly from the younger generation. There were numbers floating around.
Yes, those platforms are American, and the companies can pick whom voice is heard. They can amplify one side, while silence others. But this isn't the point.
1. Ukrainians create narrative, their government, and even the common people;
2. There is no other side, no Russian narrative to silence, it's just what Putin said before and that's it.
Even in Russia the govt. not just quite about what's happening, but they discouraged/banned media outlets from talking about war or invasion, or assult and whatever. There is no propaganda going there depicting successes, the heroes of the fight, or how the enemy is evil.
The last part, showing an evil enemy in this conflict is especially hard for Russian leadership, because when the war is over, and if they win, they have to set up a brotherly Ukraine, who counts as a friendly nation every Russian loves. This is hard to do when just before they were called evil. Or they have to incorporate Ukraine in the Russia, and it will be hard to tell people, that "hey 10 minutes ago they were evil, but now we stand together against evil west".
There was some talk about nazis and denazification, but I doubt anyone thinks whole Ukrainian army is nazi.
