Even FLOSS enthusiasts need to eat. Money don't come from writing code by itself, they come from sales. Or from donations. In both cases there is a lot of non-coding work. Do you want to do it? I don't. How do we call those guys who organize donations or sales? Collect requirements? Yes, there are requirements in FLOSS too, otherwise you wouldn't get donations, or support contracts, and those requirements are coming from the people who pay. Let's call everybody developers, only some won't write code and would organize coders, gather requirements, distribute payments. Wait, those people are currently called managers.
