I find it very hard to believe they don't promote content intended to elicit an emotional response to drive engagement in China the same way they do everywhere else.
I was referring specifically to American companies. They don't do so in China for the simple reason that they're not allowed to operate there.
This is what the posted article is about. I cannot write a rebuttal to this that is better than what Ben Thompson wrote, and I won't. The section "A Reluctant Prescription" section is directly about this.
I can rebut this, however:
"However, American tech companies manipulate their recommendation algorithms for political reasons (in the loose sense of the word political) all the time and I'm sure not everyone in the world likes that either."
They don't do it in China.
