Free software
● “Free” - sloboda, ne cena
● “Free as in freedom”
● "Free as in beer" vs "Free as in speech"
● Besplatan vs slobodan

Zašto?
● I need, I want, I CAN
● Niko ne radi besplatno ?!?
● Neko radi zbog zabave
● Neko radi zbog potrebe
● “Novi” poslovni model
● Cena usluge, ne proizvoda
Milan Milošević, 14-16. oktobar 2009, Pirot www.mmilan.com

Zašto ja?
● Korisnik
● Cena, stabilnost, bezbednost
● Kompanije
● Kompatibilnost, nezavisnost, cena
● Čovečanstvo
● Monopol, znanje, sigurnost, nema “Velikog brata”
