Tbf, US companies brought this upon themselves when they agreed to China’s guidelines for working within the country.

Lots of industries in China have a barrier to entry for foreign manufacturers/businesses that require either partnering with a local Chinese business or rebadging your product to sell under a local Chinese business brand.

Such conditions are rife for IP theft. Especially in a country that is famous for ignoring IP laws of other nations. Shenzhen doesn’t even leverage IP laws at all, it’s the wild west.
