Why? It's nonsense. If the `net really worked that way, no one would even be concerned about censorship on social media or Discord, because it wouldn't exist.
This is somewhat like saying that, if the Net interpreted damage as damage and routed around it, there would never be service outages when undersea cables are accidentally cut.
There's a lot of malicious damage out there, and the Internet has been steadily centralizing, de facto, for a couple decades now.
It's an arms race, basically. I support the defensive side here, but victory is by no means assured.
"John Gilmore, one of the founders of the EFF, once famously wrote, “The ‘net interprets censorship as damage and routes around it.”"
HN should take that to heart.
