You know regional differences exist?

I am from Moscow, I had relatives from Ryazan and Verholensk, for me drovokol is a specialised axe for splitting firewood, lesorub (and it's forest+chop, not wood, wood is only called les by people who sell it, we buy drevesina) is a person who cuts trees in the forest as a job, drovosek is a person who cuts trees for firewood as a job, drovoseksual is a person sexually attracted to trees, and drovorub sounds like a word that somebody both from Verholensk and Ryazan could say.

So the name likely was chosen to mean “(security) driver slayer." ...]: https://arstechnica.com/information-technology/2020/08/nsa-a...

While I upvoted your native insight regarding present-day language and I agree that the name is stupid, I can nitpickingly Ctrl+F "дроворуб", explained already in the 19th century as an obsolete or Siberian word, in the "ДРОВА" entry of Dahl's dictionary: http://slovardalja.net/word.php?wordid=7571

Also could be "drovosek". But you need to understand that GRU officers are so obsessed with America that they practice their English all the time and their Russian becomes neglected because of that. Look at the API they designed - not a single Russian word or a misused English word! They probably achieve this by beating you up if you say anything in Russian in the office as seen in the documentary "Americans".

"Seems like only Ukranians say "drovorub"."

How did you come up with that bit of fantasy?

> Lol. Except no Russian ever would say "drovorub".

When an authoritative statement starts off like that there’s a high chance it’s misinformation or FUD, as corrected in other replies.
