Piracy is rampant but a lot of people and especially businesses don't want to be pirates. A lot of software businesses have been successful in making casual piracy difficult and confining piracy to places (usenet, hacker-or porn- themed websites, bittorrent, limewire) that most of their target customer won't feel comfortable going. They can't absolutely stop piracy but they can make it a lot less appetizing than the "all you can eat for free" that it used to be.
