So 3% of the pop uses Linux. I shouldn't be surprised that 3% of those use Debian. I WOULD be surprised to find that more than 1 in 10k has EVER used xsnow 1 in 1M running it continually. Note this is actually wildly overstated. I have not even touched on the settings which would show flags.
Then we have to imagine they run xsnow all the time and somehow don't notice the dangerous political stuff OR run it for the first time.
If we start with 140M Russians this has certainly never happened and will almost certainly NEVER happen.
It is actually far more likely that someone should actually get caught using it trying to see the flags and have to explain that to their boss.
