> So, what is so special about programming that makes people want to share their work for free? I created my engine for myself, I guess a lot of open source projects start with one person solving his problem/having fun. I open source it because: * money is not everything, it might bring value to some people, but I doubt people would be willing to pay for it * even if it's open source it does not prevent me to earn money with it * I benefit from people using it - submitting patches, reporting problems, testing on different hardware * it can bring money in different ways * if I share my property (e.g. car, flat, computer) with somebody else, it limits my use "rights", if I share software, it limits me in no way
