Why should I be concerned?
Don't be mistaken: the core of the problem is the Chinese government, not the Chinese. Chinese are fucking awesome, the issue is how their government massively controls them.
They are, effectively, an authoritarian dictatorship that shuts down anything that doesn't agree with them, including things like killing thousands of Uyghur, the Tiananmen Square massacre, the repression of Hong Kong, and much, much more.
Do you really want to financially support these companies that obey anything the CCP says to them? That's the real question.
