I think you're wrong on this. Maybe you're right in the number of developers but most free software is paid to be produced.
I bet Google alone (and is not the only big company that produces free software) produces more free software than all the volunteers together.
We could debate about numbers and quality, but it's beside the point.
The point is that it was questioned whether people would do anything without monetary compensation.
The answer is clearly:
yes, they have and they will.
I don't think you can convince me that the scientific can tell you what to do, either with a video or with logic argumentation.
The seed of Nietsche is inside of me. I can't confuse science with morals anymore.
Finally, you admit that you have a personal belief, which cannot be changed, regardless of whatever evidence is proposed.
I guess that kind of ends it.
Faith over reason and reality.
