That depends. China, Iran, and arguably France are. The EU may be in the
very near future. And if the network is being actively (electronically)
attacked (flooding etc), which is not yet legal for the RIAA etc in most
countries, a darknet is better.

How so? If you are on opennet, you know your peers' IPs and can run
correlation/timing/etc attacks against them. If you are on darknet, you
know your peers' IPs, and can run correlation/timing/etc attacks against
them. I don't see why darknet is less secure.

Not true. YOUR PEERS know exactly who you are. That's it! Their peers
don't know who you are, nor does the rest of the network.

Still nonsense.

How is it protected against on opennet? Correlation and timing attacks
are quite possible on both opennet and darknet, but on opennet you can
identify every node and connect to all of them. Defences against
correlation attacks are hard, and even more so on opennet, because we
have even less chance of knowing which nodes are "real".
