The ban had bi-partisan support. So why should Biden stop it if he agrees with it? A major adversary (China) owns a main communication network in the US while the US and other Western countries are not allowed to operate such networks within China. You don’t have to agree with this of course but it’s not unprecedented for the US to restrict the reach of foreign governments. In the past radio waves were restricted in a similar sense.

That is my point. The Democrats made themselves look very bad with this situation and Biden did nothing and supported the bill anyway and just signed it.
In fact he replaced Trump's original EO with a worse one which includes still supporting the TikTok ban and Biden signed that last year which made it so that if the Democrats won the election, then TikTok would have been still completely banned with no reversal whatsoever.
In effect, those who voted for Biden or Harris also were voting for a TikTok ban, which that is beyond hilarious as everyone saw that he didn't halt the ban.
