I do remember reading, earlier in the war, that many Russians who fled wound up coming back to Russia as they were being lumped with Putin and being blamed for the invasion (LOL). Don’t know how widespread that was, but it does make sense that people who are brainwashed to hate Russians would have trouble thinking there are any good ones. After all think USA, during WW2 with the Japanese...although that didn’t take brainwashing by the Neocons.
The article is old news. 90% are already back.
Some of those Russians may have found a way around a general prejudice against anything Russian, simply by saying they were Ukrainian. The farther one gets from the actual conflict, the fewer people can tell the difference.
They many of them look the same slavic way, and speak with the same slavic accent. For the sake of survival,they “identify as” Ukrainians.
