Because if it did, we'd know about it. If we can get researches from Russia to expose their country's nefarious dealings, at the threat of death, we could easily get French, or German, or Canadian, or British, or American, or Czech researchers or whistleblowers exposing American propaganda campaigns.

Hell, look at Twitter/X. It got acquired by a mental guy who was screaming about government propaganda and censorship (while doing Nazi salutes). Do you really think that if there was any government mandate to do anything like what the Russians are doing, he wouldn't have exposed it as "SEE, I TOLD YOU BIG GUBIMNT BAD!!" ?

Because most propaganda I see online seems to have a clear direction, and because of some not-so-recent "scandals" where a bunch of American influencers/grifters were discovered to be paid by russia to incite civil war.
