I specifically avoided saying this. By providing those links they 'enabled' downloading of content illegally.
Considering that the US government forbade the export high level encryption, it's not hard to think they would also forbid any peer2peer communication not going though a "certified and approved" server, if the winds had gone that way.
The bottom line is, crimes should be illegal, tools should not be illegal, even if they enable crime. If you have a tool that can ONLY be used for illegal purposes, you might have a good case, but even pirate bay had links to legal content, that got taken down along with the links to the illegal content.

The difference is that the ostensible intent of these products is to enable consumers to make archival copies.
What is the ostensible intent of TPB?
Edit: found a link https://en.wikipedia.org/wiki/Private_copying_levy
Many people misunderstand this, and think it is a levy to compensate for illegal copying. That is not, and has never been, the purpose. This misunderstanding is also one of the common arguments against the levy, since it gives the impression that even though some copying may be illegal, it is compensated.
And you also argue that basically providing links should be illegal. Since TPB doesn't do any of the copying, it does not host any copyrighted content itself, it's just a central index. So until the content industry got their way in the courts and laws were altered in various countries this wasn't illegal at all. And he is fighting against the meta-information being outlawed. Pretty much the same deal as illegal primes.
