Fair enough.
When you're talking about providing a service primarily for the purpose of enabling and so forth, the problem, it seems to me, is that if the service is primarily used in a way that, in fact, is for infringement, then that escapes it.
What the officials are telling us is that there would be some groups you don't want to catch with this provision, and I understand that. What I don't understand is why, in the case of a site that's primarily used for infringement, you wouldn't want to catch it. He's saying that it's a question of policy. Your colleague seems to know the answer.
