Some startups are going ‘fair source’ to avoid the pitfalls of open source licensing | TechCrunch
New alternative category to 'closed source' could help companies monetize software in the open -- without going all-in on open source.

Open Source is a cost-allocation system
Because the right to use the software is not tied to payment, the license does not connect the people who benefit, the people who decide, and the people who bear the costs. Projects have to build those connections deliberately through governance.

Open Source Software and Corporate Influence — Andrew Lilley Brinker
Open source software projects are frequently enmeshed with the interests of corporations. We should update mental models of who works on open source accordingly, and build or modify power structures to be more resilient to corporate capture.

Open Source infrastructure deserves a business model
Open Source infrastructure is essential, invisible, and chronically underfunded. A more sustainable approach may be to connect the cost of running that infrastructure to the organizations that rely on it most.

Something Big Happened in 1998
It is reasonable to accept that OSI founded Open Source with the Open Source Definition.

NSF investing in secure open-source ecosystems
Open-source software is ubiquitous, supporting artificial intelligence, data science, cloud computing, telecommunications and scientific research tools. Despite these benefits, the number of open-source developers is relatively small, and many projects lack sufficient resources, slowing the pace of innovation and making maintenance difficult. In addition, weaknesses in open-source software, such as security flaws, supply chain risks or insider threats, can spread across many connected systems. In extreme cases, these weaknesses could lead to large-scale failures that affect national or global systems.

The just-announced Open Source Endowment is now on Bluesky, and we're open to your ideas on how to identify critical OSS projects 🙏
Open Source Endowment
We heard the Bluesky community cares about Open Source, so we showed up 👋 Our endowment dedicated to supporting Open Source maintainers is already at $729k, and we're developing a model for distributing our first funding round. Have ideas on how to identify critical OSS projects? We're listening.
We just launched the Open Source Endowment, the first endowment dedicated to supporting Open Source maintainers, with $693,000 raised already. The world depends on Open Source, but making our ecosystem sustainable is a complex task. I hope that, with community consultation, the Endowment can help 🙏
