I am not a supplier
I don’t follow the author’s logic at all.  Just because you don’t have a business relationship with the end user doesn’t make you not a supplier.  If you make software available to others to use, you are supplying the software to them.  You are therefore very clearly a supplier.  Pretending words don’t have any meaning doesn’t help to resolve the problem.<p>The fact that you don’t have a business relationship changes the nature of your obligations to others - they are voluntary - and that in fact is at the heart of why software supply-chain is a problem.  You have much more control over suppliers that you do have a business relationship with. As a community we have grown accustomed to moving at a pace that would not be supportable were it not for a network of volunteers around the globe maintaining and developing all manner of software and making it available as open source.  It would be an enormous cost and reduce velocity significantly were that not the case, so I’m very greatful that they do this. During my career I have also made some small open source contributions myself.  But that doesn’t make those people not suppliers.
