Renata, if you go on any Russian website you will find that all works published even after 1973 are displayed and not in a thousand years will anybody try to persecute anyone. Moreover the way Soviet mentality was that everything is common. So published works in the Soviet Union could have been used for any purpose. That is the way it is now in Russia.   

In the US there is a clause The defendent is assumed innocent until proven guilty in that case until wiki is actually accused by an external, ie, Russian author (which is less likely to happen than the moon falling from the sky). It is wrong to just have some vigilante make rules on images that he does not even use himself
