That's the way the Chinese Communist Party rolls. If it can't control individuals, it controls the platforms, either directly or through proxies. It started with mass media (https://freedomhouse.org/blog/media-control-china-model-comp...), social media, the Internet (https://www.bloomberg.com/quicktake/great-firewall-of-china), and telecommunications in the PRC, expanded to "overseas Chinese" communities in Southeast Asia, Australia, and North America (https://www.rfa.org/english/news/china/monitoring-0327201811...), global tech companies (https://money.cnn.com/2018/04/05/news/economy/china-foreign-...), and now global social media communities (https://mashable.com/2016/11/22/facebook-censor-china/#PGexF... and https://news.ycombinator.com/item?id=19121882).
