People will be trading MP3s, pirated games, and recipes for bombs on the Internet forever, and there isn't really anything anyone can do about it. There's no way you can monitor everyone's actions on the Internet. Warez groups have hacked versions of computer games on the 'Net before the games even hit the shelves. Yet it's these same hackers who write many of the most intelligent and technical reviews of the games, which encourage people to buy the game. But Quake's now the biggest game in the industry.
Companies are just mad because consumers have the advantage now.
Companies need to grow up and get with the times. In the age of computers and information, individuals are able to do more and more what before only big-budget productions could handle. Times are a'changin'. The more you resist, the more the Internet is going to fight back. So embrace the 'Net, or it'll burn you.
