I'm not trying to affect an objective morality to say it's "wrong", I'm just saying the US does it too. So let's not get up in arms about supposed Chinese internet commenters or Russian fake news.
Why not get up in arms about it? One is done in support of a flawed nation with democratic and freedom ideals, the other is done in support of a murderous authoritarian regime that wishes to annihilate democracy and freedom. It's perfectly reasonable to be up in arms about it.
