I haven't been at Google in 5 years but I worked with a lot of Chinese coworkers from all three of mainland China, Taiwan, and Hong Kong when I was there (as well as ABCs of those descents). Honestly, I never saw a Chinese employee get into a political argument. Mostly they were just happy to be in the U.S. and draw a Google-level salary. ABCs (including myself) would, but usually about American politics, not Chinese.

I think most Americans underestimate the extent to which most Chinese are apolitical and pragmatic. Chinese culture doesn't have the tradition of civic engagement and vigorous debate that Anglo-American culture does, and skews more towards Exit than Voice. A typical Chinese response to a looming civil war is more akin to "Well shit. Better emigrate (if I can) or pay off the right soldiers and officials (if I can't) so this doesn't harm my family" than to demonstrate in the streets and call for the ouster of the leaders in question. This is a double-edged sword: it's how the CCP maintains social controls that would be unacceptable violations of civil liberties in Western democracies, it's also behind the "model minority" image of Asian-Americans, but it also means that you don't get a lot of disruptive political talk in groups with Asian immigrants.
