It's not a "tendency", it's truth. All people you mention are Russians because they were living in USSR, speaking Russian language, worked in Russia and for them Ukraine was an administrative region. Not to mention the fact that the country that denies Soviet legacy and achievement does not have moral right to attribute anything that has been done during the period to people and regime which despises their own past, legacy, sacrifices, relatives, and denies everything that has been done. So ridiculous.
