Thomas Depierre, writing about the concept of the Software Supply Chain in the context of open source development:

We are not suppliers. All the people writing and maintaining these projects, we are not suppliers. We do not have a business relationship with all these organisations. We are volunteers, writing code and putting it online under these Licences. And yes, we put it online for people to use them. But we do not get anything from it.

He goes on to discuss how, importantly, licenses such as the MIT point this out (in all caps):

If you use this, I owe you nothing. At all. We have no relationship. I put this up online on the condition that if you use it, all the risks are on you… So all your Software Supply Chain ideas? You are not buying from a supplier, you are a raccoon digging through dumpsters for free code. So I would advise you to put these rules in the same dumpster. And remember. I am not a supplier.

That raccoon line reminds me of a now-ancient meme you might still enjoy…
