> but OSS and business software development is frequently short-handed in people who can actually make the software

But you're begging the question here. I'm not the parent commenter, but it is not self-evident that the programmers/developers are the main class of "people who can actually make the software", not even in a literal sense, since software is not just its lines of code, anymore than hardware development is factory assembly.

For example, in "business software development", there are product managers and other business-facing people who have input on and make decisions, for better or worse, about software development. How is a programmer's contributions to making the software more significant than those of their product/business colleagues', if the latter have failed to cultivate paying customers?

that's why we need to have very clear, concise conversations about contributions and what goes along with those contributions. being able to have those conversations without being polarized on either end ultimately helps move the conversation forward.
