      • License : free for anyone to use
      • Richard Stallman – father of FSF
      • Restaurant
      • Restaurant and secrete recipe
        • Without, you can't prepare same food at home
      • The recipe is source code, and restaurant is just API
      • Printer and driver
    • … if you can cook, then why to go to restaurant
      • Your own combination and customisation
      • No dependency on chef and servant; and the restaurant
      • Take help of your neighbor to make better recipe
      • Good that you don't need to sign agreements
    • Freedom
      • It has meaning with freedom of every sort
      • Almost cost free, community driven
      • No dependency for service and support
    • Simple four points
      • The freedom to run the program, for any purpose
      • The freedom to study how the program works, and change it to make it do what you wish
      • The freedom to redistribute copies so you can help your neighbor
      • The freedom to distribute copies of your modified versions to others

    • Enough... let's go precise
    • + and -
      • Possibility of long term development (Firefox)
      • Save money – no license
      • Lack of community strength
      • No guarantee about support or development
    • Why no FOSS ?
      • Sometimes marketing and advertisements
      • Preinstalled
      • Its OK, I am good with pirated copy
      • Some community or project is just slow or dead
      • No community initiative for specific domain
      • Errr... Linux? which OS?
    • Then how to earn ?
      • Charge for service and support and not product
        • Cynapse (cyn.in), zmanda
        • Cost of fruits / veggies and delivery
      • FOSS projects as raw material to make other products – license policy matters
      • Pay for customisation (CRM & ERP products)
