There are legitimate reasons to be concerned by these constant attempts to attack certain technology or websites. Personally, I think that having a society that thinks that censorship is a good way to deal with ideas you dislike, which is where we're heading if this keeps up, is a lot more dangerous than intellectual property theft.
Hell, it has been known for years that certain ISPs even go as far as to throttle ALL bittorrent traffic and despite what the MPAA would like people to believe some of the bittorrent use is perfectly legal. World of Warcraft actually uses bittorrent for their patches.
As well, there are the facts that: -Laws have been passed that are so excessive in punishment that judges are actually slashing the penalties, and there are even stronger laws that lobbyists are trying to get passed. -This idea of protecting intellectual property at all costs has led to modern electronics devices being very rigidly controlled to the point that if you try to modify YOUR device to just install linux or something, you might be a criminal. -Copyright lasts a ridiculously long time. There should definitely be some rights so that the creator can benefit, but almost a century is too long.
This is clearly fallacious, I don't know why people keep using this technique, and we really should give it a name so that it can be referred to by shorthand. (Any suggestions?)
If you happen to find a person in the set A intersect B, then you've got a case against that individual. But nobody seems to go to that much effort.
Most HNers probably believe some sort of property rights for software (or even blog designs). May here would argue that the GPL is a great license and violators should be punished.
You can also often read that Hollywood and the Music Industry are producing worthless crap, but yet The Pirate Bay is dominated by commercial entertainment, not by Creative Commons content.
Much of it is certainly an emotional reaction to the aggressive behavior of RIAA/MPAA, but it really is sad to see so little capacity to see things from a different perspective.
