Maybe because there might exist propaganda against the Chinese government? If Twitter has evidence for Chinese propaganda on a US-based site that's inaccessible to the Chinese population, wouldn't it be reasonable to suspect that US propaganda that targets the Chinese government exists too?
The above is just my opinion, but I think we're detracting from the main issue in the parent comment, that the term "WuMao" can be considered a derogatory term. Tell me if I'm wrong, but many terms started off neutral, but turned derogatory over time. The example that comes to mind is the N-word that rhymes with aggro, I'm not even sure if it's okay to use that so I'm self-censoring.
