> MSN Messenger in China was run by MSN China, a separate company run by Chinese residents (as required by Chinese law)

Microsoft retained a 50% ownership of MSN China, just check the link you cited. Microsoft also retained the full ownership of the MSN messenger software while MSN China was just in charge of its day to day operation in China.

Also interesting to see that millions of Tesla EVs are being sold in China, hundreds of millions other American cars were sold in the past, but when Chinese EVs try to crack the US market it sudden becomes a national security issue.
