A guess: It's getting points because many people have reposted it; all subsequent posts end up as up-votes for the first post.

I think people post things not only to have a discussion, but because they think they found something others should be aware of.

There doesn't need to be a comment on every post. If the article said enough and people agree with it, it doesn't really require a comment that just says "Agreed." or "Great article."

Maybe they're speechless from the government and RIAA getting away with such a blatant violation of one's civil liberties. I hope this goes to trail so that the site owners are compensated and so that this never happens again. Shame on the government; They're supposed to protect the little guys.

It has been on hacker news some months ago..

The linked article was posted yesterday, so it hasn't been on HN for several months. Perhaps the topic of the article?

What is there to say, really? As the article points out, the RIAA has a serious amount of influence on the government, and they can do whatever they want.
