Apparently the people or person who did that had left some time ago, someone else found said file and made a big stink, leadership apologised, but not in the right way(?), there was some expressed "outrage". Then the leadership, obviously out of frustration, said no more politics allowed at work and offered redundancy to anyone who disagreed.
Seems all forgotten now which is good because the whole thing was dumb. Someone thought having the surname Wang was funny. Ok it's childish but they left already so who gives a shit? One side asking that we all be outraged by this behaviour, sorry no. Another side saying employees can't talk about politics, sorry that's stupid.
Anyway, that was my remote reading of the story, I'm sure I missed the important nuances. It shouldn't have been a public thing anyway imo.

I didn't see that in the article in you linked. Are you referring to another source? Could you link it?
