@mattly @stonebear @janl As for your post:
1. You're taking "supply chain" too literally. It's not a good term. The loosely-collaborative software phenomenon that emerged merely got a professional-sounding label slapped on it, even though it doesn't have a good real-world analogy.
The fact that you don't fit a definition of a "supplier" doesn't mean you're not involved in this software-thing, only that the label given to it doesn't properly describe who the participants are.
@mattly @stonebear @janl 2. And you've used "FOSS" term for what is OSS, but that's not surprising, since it was designed to be confused.
ESR's OSS has intentionally hijacked FSF's collective ideas to shift them into a system that can easily commercially exploit unpaid labor. The fact that we have a mountain of OSS code for which nobody gets paid, and companies can resell for free is OSS working exactly as intended.
