I mostly agree with the article, but the title is downright wrong.
Even a relatively literal read of the words "supply chain" is reasonably appropriate, even for FOSS. Wikipedia's current definition for supply chain is:
> In commerce, a supply chain refers to the network of organizations, people, activities, information, and resources involved in delivering a product or service to a consumer.
There's nothing in that definition that necessitates a formal agreement, support commitment, etc.
