I’d say China is one of the countries which really needs dweb, but it is kinda different. Perhaps they haven’t tried DHT peer enumeration, by experience, and torrent is quite fast and not blocked here. They have developed GFW, so they will probably have the capability when they think they need to.
If we limit the nodes a peer can know and access, the network will become less open and robust. Is F2F network the only solution then ? Dweb would be way less interesting without DHT.
I remember that some people expected China not to ban the protocols because of economic concerns. They have banned cryptocurrency, private education and gaming industry. If dweb becomes a threat, they will ban it instantly as long as possible.
China is also exporting their censorship technologies I’m afraid that there will be more countries deploying these things. Optimistically, when they should have realized the threat of dweb, it would be too late, or they actually would try to ban some of it rather than everything.
