You're misunderstanding the point of the great firewall, which is to create an isolation effect on the Chinese net. Obviously a bunch of American e-refugees foils that. This absolutely is a massive change to the status quo.

He's saying zoomers are moving from TikTok to REDNote rather than Instagram/Facebook. Not that they're going from Instagram/Facebook to REDNote.
