"To all members of the open source community who take the HACKER SPIRIT seriously and use this force for the good, those who defend "FREEDOM OF INFORMATION", to those who have encouraged me since 1998 in my first contacts with Free Software, to the ones who sacrifice themselves to divulge information, to those who love their idealisms above capitalism and strive to make a better world without harming others. To all who defend these ideals, a BIG THANK YOU!"
