Digital borders should only be open and allow free traffic between allies.
edit: since it won't let me reply to posters under here. What I mean is in stopping foreign propaganda and interference. Elon Musk can't spend hundreds of millions to influence e.g. the Chinese people in ways that benefit the US.
I don't think many people separate out the "incoming" and "outgoing" aspects of firewalls, and conflate firewalls with censorship. Most of the countries that employ firewalls do both, censor as well as protect. But it's not a requirement that you must censor your own people in order to stop foreign agents interfering in your society.
This is quite literally what banning TikTok is about. Suddenly the US has decided that they don't like it when other countries do to them what the US routinely does to others.
Oh, how far we have fallen.
> Governments of the Industrial World, you weary giants of flesh and steel, I come from Cyberspace, the new home of Mind. On behalf of the future, I ask you of the past to leave us alone. You are not welcome among us. You have no sovereignty where we gather.
US owns most of the social networks, video streaming platforms and most of the classic media (tv,...).
The diffrence is, that countries like US (and many EU countries) point a finger at china/russia and accuse them of censorship, claim themselves to be free, and then do the same censorship that russia/china do.
