Going global to where ?
USA, Europe, india, global south.
USA & it's allies is going to ban it in entire region which means ban in usa and their allies region and they will also deplatform it in iOS & android. So you won't get it able to download and even download apps won't work like russian RT news .
Apps popularity depends on user the more user you have the more user you will get, that's why even simple chat app that is what app is still so popular and downloaded even though we chat does same thing. Tiktok will lose alot of users and it will be reduced to china only.
To make it global they have to use Chinese OS but every body would move to other social media if tiktok doesn't appear. Hauewi OS is still child compared to android and iOS and people won't switch to huuaei OS only for tiktok and it's loss of user would be gain of instagram and other platforms.
Like I said repeatedly to you, no one controls the battlefield.
If they want another fight, they will get another fight.
Oddly, if there is a fight over TikTok, if it is banned, those populations would be upset at their own government. LOL.
TikTok makes money for itself, but more importantly, it is a moneymaker for those influencers, who may be American.
If the US government bans TikTok, infringing on an American's right to make money off TikTok, expect a lawsuit.
Then in open court, the US government will have to convince a judge how a cat video is a national security issue.
How do you think the judge will rule? What if he/she the judge likes cat videos?
No one controls the battlefield.
