Ecosystem Mapping — Open Tech Strategies | Blog
All the power of open source comes from throwing in with your neighbors, even the neighbors you don't like very much. For most projects, the main reason to get involved in open source is to create productive relations with as many participants as possible, including rivals. Doing this well requires understanding who is in your ecosystem and how they relate to each other.
Roadmap: Open Source
After years of investing in open source software, we’re releasing our thinking on what positions these companies as emerging technology giants.
The next wave in software is open adoption software | TechCrunch
There’s a big shift happening in how enterprises buy and deploy software. In the last few years, open technology -- software that is open to change and free to adopt -- has gone from the exception to the rule for most enterprises. We’ve seen the IT stack redrawn atop powerful open-source projects, with developers opting for an “open-first” approach to building solutions.

How will OpenAI compete? — Benedict Evans
OpenAI has some big questions. It doesn’t have unique tech. It has a big user base, but with limited engagement and stickiness and no network effect. The incumbents have matched the tech and are leveraging their product and distribution. And a lot of the value and leverage will come from new experie
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.

About | Open Source Ecology
The mission of Open Source Ecology (OSE) is to create the open source economy. An open source, libre economy is an efficient economy which increases innovation by open collaboration. To get there, OSE is currently developing a set of open source blueprints for the Global Village Construction Set (GVCS) – a set of the 50 most important machines that it takes for modern life to exist – everything from a tractor, to an oven, to a circuit maker.
Reclaiming scientific publishing: Our duty to make science freely accessible to all
When we (Camille Thomas and Romain Vaucher speaking) entered academia as graduate students in France and Switzerland, we were enthusiastic about the vast amount of research available with a simple click on our university computers. However, we also quickly felt disheartened by the significant amount of research work we couldn’t access when wrapping up our theses from home. Luckily, pirates existed. Empowered by Aaron Swartz’s Guerilla Open Access Manifesto, Alexandra Elbakyan created Sci-Hub in 2011, the greatest leak of scientific knowledge of the century. We felt right in the middle of an Open Access (OA) revolution that would finally make all scientific articles, old and new, accessible to everyone. Fifteen years later, our hopes as idealistic early-career researchers have been crushed by the oligopolistic model of scientific publishing and the subtle pressures of the “publish or perish” culture that reigns over our career development. In the meantime, publishers like Frontiers, MDPI and Springer Nature, to name a few, have exponentially expanded their number of titles. They have become increasingly exploitative of scholarly manpower, moving far away from the genuine accessibility they allegedly promised under the guise of this OA transformation. Open Access is to be praised, but the way it has been implemented through the mainstream Gold and Green OA models now primarily serves the status quo of large for-profit publishers. These entities hijack public money and voluntary editorial labour for their own profit and that of their shareholders (Butler et al., 2023; Shu and Larivière, 2024). In a nutshell, to offer reader accessibility, the Gold OA model requires authors to pay an Article Processing Charge (APC; around 2,000 $/€, rarely less, and often much more) covered by individual research funds, funding agencies or university library deals. The Green OA model allows authors to upload their accepted, non-formatted manuscripts to repositories after an embargo period. While both models allow compliance with funding agency mandates, true equity and accessibility are ultimately left behind. In an article we recently published (Vaucher and Thomas, 2026), we describe the mechanisms through which we, as researchers, inadvertently contribute to keeping research exclusive while driving the publishing model down an unsustainable path. Just like our broader economy, our publishing model and the ways science is evaluated fuelled a predatory system that demands more papers, funding and prestige at an ever-faster rate (Walter and Mullins, 2019), likely at the expense of quality, diversity and ethics (Frank et al., 2023; Heen and Vogt, 2024). These concerns aren’t entirely new. What is new, however, is the growing realisation among societies, universities and funding bodies that we must move away from this system. Initiatives like the European Diamond Capacity Hub, ALMASI and craft-OA are actively paving a way forward that we, as scientists, have yet to fully embrace. In the geosciences, a collective and concerted effort is currently being made by researchers to provide fairer, more sustainable alternatives through community-driven Diamond OA journals (which feature no APCs and completely free access to published articles). Volcanica (Farquharson and Wadsworth, 2018), Sedimentologika (Thomas et al., 2023), Tektonika (Fernández-Blanco et al., 2023), Seismica (Rowe et al., 2022), Geomorphica (Lefebvre et al., 2025), Open Paleontology (Drage et al., 2024), Advances in Geochemistry and Cosmochemistry (Pourret et al., 2025), Geodynamica, jSEDI and Planetary Research are all recently created, scholarly-run journals funded by university library investments to promote better ways of publishing. Their articles are peer-reviewed, free for readers to access, and free for authors to publish. They rely entirely on the voluntary involvement of scientists running open-source editorial platforms (such as Open Journal Systems), transparent workflows, copyediting, production and final dissemination. Diamond OA journals offer an alternative path for all of us to transform our broken publishing system and reclaim ownership of our own science. These efforts go hand in hand with greater involvement in our academic societies and non-profit publishing initiatives. Ultimately, real transformation can only happen if all of us as researchers realise how inherently unfair and exclusive the current system is to labs and institutions that cannot afford steep Gold OA APCs or paywalled journal subscriptions. It also means we must collectively stop evaluating science based on journal prestige and the flawed metrics they own (Posada and Chen, 2018; Sabel and Larhammar, 2025; Simons, 2008). Only by breaking these habits can we truly make knowledge accessible to all.

A Replication Study on Measuring the Growth of Open Source
Context: Over the last decades, open-source software has pervaded the software industry and has become one of the key pillars in software engineering. The incomparable growth of open source reflected that pervasion: Prior work described open source as a whole to be growing linearly, polynomially, or even exponentially. Objective: In this study, we explore the long-term growth of open source and corroborating previous findings by replicating previous studies on measuring the growth of open source projects. Method: We replicate four existing measurements on the growth of open source on a sample of 172,833 open-source projects using Open Hub as the measurement system: We analyzed lines of code, commits, new projects, and the number of open-source contributors over the last 30 years in the known open-source universe. Results: We found growth of open source to be exhausted: After an initial exponential growth, all measurements show a monotonic downwards trend since its peak in 2013. None of the existing growth models could stand the test of time. Conclusion: Our results raise more questions on the growth of open source and the representativeness of Open Hub as a proxy for describing open source. We discuss multiple interpretations for our observations and encourage further research using alternative data sets.
