Mullaney’s article is not uncontroversial. There are substantial technical challenges that come from the Chinese writing system; Chinese typewriters were highly limited compared to Western alphabetic ones. See discussion at https://languagelog.ldc.upenn.edu/nll/?p=25776 for example
Academics whining about other academics pointing out orientalism is not unusual. I'm not familiar with Moser personally.
I am not a historian - I am only married to one. So I'll only say that from my personal experience interacting with historians who know Mullaney well (both professionally and personally) that his writing is well respected even if his social media presence is a bit much.
