Also, please edit swipes like "probably deliberately" out of your comments here. With that you broke at least two guidelines: the one against flamebait and the one that asks you to assume good faith.
Just look at the summary and maps here https://en.wikipedia.org/wiki/Eastern_Front_(World_War_II) and tell me again that I am the one nationalism baiting by pushing back against the term "Russo-German war".
But you are correct that I cant assume bad faith by the original authors. There might be other reasons.
Then things get simplified for English-speaking audience titles ...
First, fix problem with down-votes — down-votes are used here to hide alternative views on a problem, from politics to quantum theory.
Second, fix problem with off-topics — create possibility to separate off-topic branches from main branch, so users can discuss their problems without disturbing others.
Third, text contains no emotions or political battles. It's just text. Minor correction of text between two historians can be major insult to you.
