1. Open Source vs. Proprietary Software Andreas Sembrant Mahdad Davari Muneeb Khan Nikos Nikoleris

2. Open Source vs. Proprietary Software Open Source: – The source code is kept open and free for all so that everyone can contribute and use – Development is done because programming is fun Proprietary Software: – Developed internally by a company – Based on a business plan

3. Open Source vs. Proprietary Software Stallman vs. Johnson (Andreas) Ethical Egoism (Mahdad) Utilitarianism (Muneeb)

4. Stallman vs. Johnson Better for society because: Less redundant work Higher productivity when users can directly contribute People will eventually learn to donate money Copyright/patents protect the financial investment of the developer The purpose of the patent system is not wrong Pirating software is stealing StallmanJohnson

5. Ethical Egoism Right action is the action that is most advantageous to oneself in the long run + Users provide free labor - Lose control of the development + I can “steal” other people software for free, and extend it. + Become rich + Maintain control - Do everything from scratch Open SourceProprietary Software

6. Utilitarianism Right action is the action that maximizes the overall happiness for all Free for users (+) Less redundant work (+) – Implement new features instead Difficult to use (-) Boring programming tasks are ignored (-) Economy/Startups (-) – Difficult to attract investors Can be expensive to use (-) Redundant work (-) – Better to invent new things than redoing old things Easier to use (+) – Developers are paid to also do boring tasks (e.g., write documentation) Economic prospects (+) – More jobs for society – Easier to attract investors Open SourceProprietary Software

7. Open Source vs. Proprietary Software Stallman vs. Johnson: Not clear Ethical Egoism: Not clear Utilitarianism: Not clear At the moment, the largest investment returns comes from proprietary software – but this trend is slowly shifting since more companies are providing open source software (e.g., google, android)
