Tiktok is only platform which is owned by china ,rest are owned by America( meta, google, twitter etc). Platform is one of the best thing which you can have, because of platform advantage America pushes video, content of anti china & anti russia and so many people no matter how much you try you can't defeat their algorithm so you would be end up watching their content & get brainwashed. Since tiktok is not in their control so they can't twick their Algorithm for anti china & anti russia propaganda. If you don't believe me then just see views of pro china channel and any anti china channelBut bro Tiktok is an Americanized Chinese food and it taste like shit...lol
The only solution for china is that they need their own OS both mobile & laptop and their own platform which can compete with big tech companies platform and they need huge number of devlopers from all over the world to achieve that ,but main problem would be that how many people outside of china would be willing to ditch ecosystem of meta, google ,twitter and dump android & IOS I don't think it might work that much , because everybody don't want to leave those big platform where there are so many users are already there .
