Why are you so scared about it? Don't pirate things and if they do touch your connection, sue them. Easy.
The thing about suing people is that you have to be in the right within the confines of the law in order to win.
So if the government passes a law that says they can look into your connection whenever they want, you can't sue them for acting on this.
You might as well say "Don't worry, just don't be a Jew, and if the Nazis genocide your entire ethnicity, just sue them. Easy."
I don't have any counterproof on this, but my uneducated guess is that a statistically significant number of people who would otherwise spend money on the products is pirating them instead. It makes sense. Pirating things is easy, and the target demographic for software is big enough to contain some morally but not economically bankrupt characters who could afford to buy their stuff, but won't as long as they can get it for free. And if piracy was costing the industry nothing, why would they spend time and money on developing DRM? Spending money on being mean for no reason sounds like a bad business practice.
Pirating things is easy for movies and PC software, yes. Here are some things you need to realize, though:
A) The vast majority of people aren't actually as computer proficient as the people on this forum (Read: All Forums. Even the stupidest people you meet on the forum you frequent are better with their computer than a large portion of the populace). You would be amazed at how many people (even young people) still don't know how to use Word or send out E-mails. If the dude can't send an e-mail, he can't pirate your game. Have you seen the message boards on these torrent sites? Half the people there don't even know how to get their pirated software to run.
B) Pirating console games is a bit trickier, and requires you to mod your hardware and stuff yadder yadder. If somebody's going to that kind of effort not to pay for your shit, they're not paying for your shit.
C) Pirated games don't emulate the multiplayer very well. Games with online features or gameplay (such as Call of Duty, or Spore, or World of Warcraft) just aren't worth stealing. Call of Duty requires 16 GBs of space to steal (8 GB CD Image, which you then have to install), and all you get is an eight hour single player mode? Please. Even the private pirate servers suck.
Nobody ever seems to bring up the victories against pirates, either, possibly because people don't notice them. The first Mass Effect was unplayable in the pirated version because the galaxy map would break down and crash the game. You could play up until you left the huge city-station the first time, and then you were done. As far as I know, it's still like this (I have my own copy now, so I don't need to test this theory, though when I did test it, it had been out for a month). It's strange how Mass Effect didn't get any attention for defeating the pirates (though, I guess they had other things to talk about at the time).
If piracy is costing money anywhere, it's in foreign markets. Entire businesses have been set up across the Middle East (and it has been like this for over 10 years, at least, I visited one such store in Damascus in August 2001, and my roommate's boyfriend says they have several in Qatar) which are dedicated to selling bootleg video games for a dollar or two. Before you retort "But they're pooooooor", do some research to discover that these places aren't aimed at the poor Middle Easterners (who don't have computers anyways) but at the rich Middle Easterners (especially in places like Dubai and Qatar, where everybody has a maid and drives the fanciest car they can). Those people can afford to pay the same prices. Instead of trying to crack down in the West, producers should be trying to strike a deal with the Royal Families of the Gulf to get some regulations going.
