There was an interesting new post on the subject written by China Researcher Yaqiu Wang and published at Human Rights Watch. Take a look at this excerpt:
On Monday night, Clubhouse, the red-hot app where people can create chatrooms that disappear after use, became inaccessible in China, presumably blocked by the authorities. Many had expected this to happen, but some were still surprised by how fast the government acted.
Over the previous days, thousands and maybe more users in mainland China flocked to the app, engaging in discussions with users from Hong Kong, Taiwan, and the Uyghur diaspora. They spoke about issues that are prohibited in China, such as the “political education” camps in Xinjiang, state surveillance, China-Taiwan relations, and the Hong Kong protests. People from all sides of the political spectrum shared their experiences and learned the perspectives of others.
