That's a CPC threat point. They frequently put things like: "if you do this, the Chinese people will be very upset," they always use strong emotional language like "outraged" or "angry" - it's non-subtle code for: we'll force the Chinese people to harm your commercial interests. Almost any time you see something about how the Chinese people are or will be outraged, that is what is really going on. The party constantly uses that tool against any foreign entity that steps out of line. It's how they have threatened & browbeat everyone from South Korea & Japan to Britain and various large corporations. It's meant to inflate the size of the opponent on the other side, because upsetting 1.4 billion people seems a lot more intimidating than upsetting a small collection of authoritarian bureaucrats in Beijing.

If an airline refers to Taiwan, the CPC will say that the airline has upset or outraged the Chinese people, and then follow with subtle descriptions of the consequences. The Chinese people are typically overwhelmingly unaware of what is going on. What they mean is, the CPC is upset and will force the Chinese people to do something bad to hurt your interests if you don't get back into line with what the CPC agenda is.
