The underlying system, if you mean the IP layer, is controlled by non-governmental organizations like ICANN. It’s already as open as any system can be in a world of nation states. If someone is censoring you then you can host in another more liberal jurisdiction, or even with a geopolitical enemy like Russia. Sure, your home jurisdiction could still block your site. But this is a problem of laws, it’s not something that has an easy technical fix. Same goes for net neutrality, which is a legal concept not a technical one.
