What is Open Source?
summary
Argues that the OSI definition only certifies licenses, not the broader concept of open source, and proposes a 2x2 quadrant (OSI-certified vs not, follows community norms vs not) to classify projects — examples include Android, Redis, MongoDB, Elastic, Grafana, GPL+CLA relicensing, plus inner source and ethical-source cases. Claims this framework predicts risky moves and gives concrete signals to watch: ease of contribution, maintainers all in one company, governance and trademark control. Useful if wanting a practical checklist to assess open source in letter only versus open source norms.
