You know that there is no Facebook in China? The same for Instagram, Twitter and YouTube.
Even Google Search is not available in China.
And not because those companies didn't want to work in China, simply China forbade them to do it.
Funny thing, even TikTok in China is blocked... Chinese audience have Douyin from ByteDance.
So it isn't like this that "bad US is doing something to poor Chinese company"
There is no Facebook in China for the same reason there will be no TikTok in the United States. Both Meta and ByteDance won't let another country run their business. Facebook was given the chance to operate in China if they complied with China's rules
