The Chinese government may not be a bastion of the rule of law, but they at least seem to still have a functioning antitrust enforcement.
This had nothing to do with antitrust.
What does it have to do with?
Stopping Chinese nationals from freeing assets and funds from the grip of the Chinese government.
It stops Singapore washing.
Interesting to know that Meta has business in China and needs the government's approval.
About 10% of Meta's ad revenue comes from Chinese companies reaching a international audience. They also manufacture most of their wearable devices in China.
This was pressure on the founders and the fact that they have their families effectively hostage, not on Meta.
