So I like everything that Zed Shaw wrote on this topic before. Whether his points were mostly or somewhat correlated with her point of view, I don't remember, but it was full of great ideas. His project Mongrel, allowed other for profit Ruby projects exist in the way that the community needed. A good analog of getting paid with 'free to use' theory are calculators. We know that 2 + 2 is 4. The theory is free and out there. If you want a thing that does the calculation for you, then you gotta pay $5 for a calculator. CS theory is similar. Each tool or abstraction builds on a previous one. While we can't charge at each step of abstraction, we can at least license accordingly to encourage sharing of profits made from it's use.
