Probably because these are not "historical facts". I mean, genocide? Harvard University tried to exterminate the Russian people? Who knew a bunch of academics had that kind of power...
Of course, this also neatly ignores the responsibility of Russian politicians for their own country, which was hardly under foreign occupation at the time.

So, yes, "basically genocide" is an appropriate choice of words.
