>Don't think he truly represents the USA, once he is out we will almost certainly have to wash our collective hands of him

You can't wash your hands of him, He is democratically elected as a representative of you.

But I agree that TikTok is yet to prove itself. That said, I think it is an example what is about to come if the USA doesn't close off its market(which will lead to others close off their markets to foreigners and the internet will become balkanised) or break up its current Internet companies situation. Sure, FB and Google will continue to earn an enormous amount of ad money in the years to come just like Nokia continued to sell it's phones until it couldn't anymore.
