Many countries in Eastern Europe have radically different interpretations of history. The nationalists from each country will try to establish their own ethnicity for persons of interest. They will try to add editorial comments or hyperpartisan sources to all kinds of historical articles. There are edit wars about what language to use for what city in what era. I would guess that this is the case for many other regions of the world.

Russia is the major player in pushing disinformation in historical articles about eastern europe (and not only). It works on it systematically by using both hired editors and volunteers on scale as well as producing “backing” materials.

Framing editors who are trying to keep up with cleaning all this mess as bad actors is understandable if you support the goal why russia is doing that.
