You might reasonably be describing the current TikTok algorithm, but companies often modify algorithms over time.
Take an example from Russia - instead of banning youtube, they just make it crawl and stutter, so fully controlled rutube/dzen/etc start to seem more viable, but it's not too bad to decide to go full VPN. Non-technical people don't even realize that it happens and write it off as some youtube-related network issues.
Of course that is an awful attack on freedom, but you can get real or get rekt.
