> curious: what do you think that is? behind the trend thing? or a cultural thing? more popularity of talking on phones?

Is it because the authorities are unaware of it and haven't blocked it, so there's a brief window where uncensored conversations can take place?

Something like that happened with Clubhouse in China: https://www.nytimes.com/2021/02/08/world/asia/china-clubhous...

I wish I could tell you, there is something to be said about 1) being live with no recording so records of dissent dont exist and 2) like the other commenter said slow government response

I suspect it's a lot of small things and social network multiplicative effect
