There's ups and downs about pirating softwares (Note: I am not saying I am for nor against pirating).
For example, to some people that Sam & Max Episode 1 demo seems too short even for a demo. I can say that some people may have played a pirated copy of the episode 1 all the way to the end and they like it so much that they're buying the full season.
At the same time, there's always way poor, poor little kids who doesn't have access to credit card or know anything about the hard working labor of programming, developing, designing a video game, no matter how long the game is, those people who work on the game deserve a share of the profit from the software, but yet, they just don't understand that concept. The only concept they know is INTERNET = EVERYTHING IS FREE.
