Executive Summary: What is it?
The project is open source, but a single for-profit company controls it: it holds the copyright to the code, or a contributor agreement gives it the right to relicense contributions, and it sets the roadmap. It effectively decides the future of the software.
CFO / Business Impact: What does it cost/risk?
- License Volatility: A company that holds those rights can release future versions under a different license, for example moving from an open source license to a source-available one such as the SSPL. The updates you depend on could then require a commercial agreement, or a move to a community fork.
Technical Reality: How does it work?
- Funding and Pace: One company funds most of the development, so releases can come fast and on its schedule, and the roadmap follows its commercial priorities.
- Support: Paid support, where offered, comes from the company that writes most of the code.
