1) In FB's own words: https://about.fb.com/news/2022/02/meta-is-absolutely-not-thr... so mass media just put the word into FB's mouth

2) On "China didn't ban ...", that's the case for Google and Linkedin China, but it's actually a kind of "soft" ban that the cost to meet the regulatory requirements is too high to afford even for biggest companies in the world.

3) FB case was a bit different. It was never given any opportunity to operate in China, so FB didn't "chose" to leave. We would never know what FB would do if given the chance. Maybe leave all user data there inside the great wall, as Apple does in its special version of iCloud in China.
