FSF - ACTA threatens free software
« ACTA threatens free software. It makes it more difficult to distribute free software (...), it will make it harder for users of free operating systems to play media (...), it creates a culture of surveillance and suspicion, in which the freedom that is required to produce free software is seen as dangerous and threatening rather than creative, innovative, and exciting. »
