If anything I'm not trivializing it enough.
There are dozens of companies with vastly more cultural literacy vying to manipulate you into buying goods every day. Amidst the sea of "look at my notification! Look at my recommendation! ANNOYING clap AD clap TIME!!!!!!!", why do you think some random overly angry/insulting recommendation with a bizarre or nonsensical framing coming from China is going to change minds rather than be ignored?
Foreign propaganda tends to gain traction when laundered through someone people pay attention to. (E-)celebrities, political figures, charismatic activist figureheads. Not a recommendation algorithm endlessly exploited by advertisers to get a tiny crumb of attention from.
The Intelligence Community and the Department of Defense have minimal literacy in the economics of attention and it shows.
