What makes you think they have "absolutely no problem with it"? You don't think it would be operationally simpler and more profitable to allow communication between Chinese and non-Chinese accounts?
No, not really. Companies operating in China silo their services because Chinese laws demand access to servers, and by siloing the company ensures that the Chinese regime does keep it's hands off stuff they have no business accessing.
Siloing services in China has zero to do with CCP's demands and everything to do with a company's self-interest.
CCIP demands access to servers -> companys silo to protect data from CCP
But then claim siloing has "zero to do with CCP's demands". Having trouble understanding this logic.
