Free Software Libre Software Open Source Software FLOSS 

Open Source is not a religion Open source is a public good (as in economics), And is good karma (as in ethics), And has a tribe that tries to enforce norms. 

The Four Freedoms 0. Run the program for any purpose. 1. Study how the program works. 2. Redistribute the program. 3. Improve the program, and redistribute the improvements. 

Open Source Definition 1. Free Redistribution 2. Source Code Availability 3. Derived Works Allowed 4. Integrity of the Author’s Source Code 5. No Discrimination Against Persons or Groups 6. No Discrimination Against Fields of Endeavor 7. Distribution of License 8. License Must Not Be Specific to a Product 9. License Must Not Restrict Other Software 10. License Must Be Technology-Neutral 

Commercial Open Source Provides customers with: ● A focus on support ● Vendor independence ● Vendor risk mitigation ● An improved negotiating position ● Compliance with policy ● Fast adoption (no purchase necessary!) ● An ancillary social benefit And has a reputation for: ● Low price ● Security ● Innovation ● Transparency ● Interoperability 

Open Source is Good for Business ● Grow the ecosystem in which we sell ● Drive adoption of standards ● Foster innovation by leveraging community contributions ● Encourage 3rd party contributions that can benefit customers ● Increase the difficulty of competitive followers in bootstrapping a business ● Gain brand recognition and community marketing ● Grow customer goodwill and loyalty ● Be an on-ramp to paid offerings 

Strategic Tools 

Open Core is a Balance Adoption Upsell 

Open Business Models Pure Play Source Available Everything is open source Revenue comes tangentially: support, hosting, training Source is available. Development is public. License is proprietary. Open Core Parts are open, parts are closed. Revenue comes from upsell to proprietary features. 

Types of Licenses Open Source Gift Apache Sharing with Rules GPL In-Between LGPL Bruce Perens, 2009 Source Available Time based BSL All rights except . . . CCL, SSPL Mixed open and closed Elastic License

Project Control Community Governance Corporate Governance ● Multiple copyright holders ● Anyone can merge ● Community consensus process Pros: ● Broad adoption Cons: ● Hard to achieve alignment ● Susceptible to “tragedy of the commons” (lack of polish) ● Single copyright holder (CLA) ● Restricted merge rights ● Corporate vision Pros: ● Customer focus Cons: ● Often narrows use cases ● If you disagree, you have to fork 

Effective Open Core Differentiation ● Pay attention to the incentives: Cooperation vs Competition ● Horizontal vs Vertical: Horizontal drives adoption, Vertical drives value ● Technical difficulty: Easy stuff will just be replaced
