Hopefully if some of their better games do well on Steam they'll realize that the real way to address piracy is to just release a quality game and charge a reasonable price for it. The die hard pirates are going to pirate it no matter what you do, but if it's a good game and you're charging a fair price for it, people will buy it. Even people who initially pirated it will frequently buy games that they considered good after the fact.
I'm actually surprised we haven't seen more game studios go back to the old shareware model we used to have with things like the original Doom. Release the first 1/3 of the game as a demo that's entirely free. That let's people see whether it's good or not. Then release the last 2/3 of it at a reasonable price. If the first part was good, people will be lining up to throw money at you. If it wasn't then go back to the drawing board and make a better game.
