Lack of purpose: social media app that is allegedly heavily spying on its global users in favor of CCP would not be useful in a territory where Chinese government already forcefully requires anyone to disclose user data to them.

External and internal optics: anything available in Hong Kong yet unavailable in China is liable to make Hong Kong appear separate of China.

Collective mindset: Western UGC, even if censored to a degree, carries values and notions that threaten CCP’s power and influence over given territory. (I wouldn’t be surprised if TikTok’s Chinese sibling is going to be heavily promoted in Hong Kong, if it isn’t already.)
