New Episode Dropped! Is the future of open source under threat… or is it simply evolving into something bigger? We sat down with Heather Meeker and Sabir Ibrahim, co-founders of @ChinstrapC, for a deep dive into the wild “frontier” of Commercial Open Source Software (COSS). Watch the full episode here: youtu.be/MxUBA5Of75o?si=VKYU… In this episode: 1) Defining COSS: It’s not just releasing code — it’s building serious, profitable businesses where open source is the product. 2) Legal Frontiers: Why technology always outruns the law and how “community practice” quietly becomes the real rulebook when case law doesn’t exist yet. 3) The AI Challenge: Machine learning is blowing up every traditional licensing assumption — can AI-generated code even be truly open source? 4) Sustainability: Why a vibrant, healthy community isn’t just a nice philosophical idea anymore — it’s a non-negotiable business imperative. 5) Plus: An exclusive first look at cossmology.com/, the new “Crunchbase for COSS” already tracking 1,200 companies in the ecosystem. Whether you’re an entrepreneur, investor, or builder, this is your masterclass on the business of open source. #OpenSource #COSS #AI #SoftwareEngineering #TechPodcast #Cossmology
