Open source != open contribution or project The most well known project following this is SQLite. There are many reasons to do this: - ensuring that the copyright is fully owned - ensuring security by reducing the likelihood of someone submitting secretly vulnerable code - not wanting the overhead of running an Open Source Project - wanting ultimate control on the architecture of the tool - early stage of a rapidly changing codebase There is a danger that "gate keeping" the concept of open contribution == open source, reduces the motivation of people to open source their code. All open source, no matter the contribution policy, should be applauded.
