Why?  Isn't it obvious?  The FBI is ignorant.  Their ignorance is a direct result of manipulation by the entertainment and software industries who have continuously failed for the past 30 years to understand the way the world truly works.

They will never stop piracy.  If they even want to try, they should start doing it in a place that makes a little bit of sense.  Start knocking out pirate DVD vendors on the streets, bust and bury mass pirate CD/DVD replication plants, stop China from pirating (hah!  good luck!) or perhaps anything more useful than illegally arresting and detaining hobbyists who aren't making a cent from this.
