True, there are commercial aspects to the open source movement. However, there are many more aspects and angles.
There is the culture of 'gift giving' as documented in many books; and there is a cause-and-effect in that culture.

Charity, kindness, gift-giving, all are parts of the complex cause-and-effect equation of life as we perceive it, just as commercial forces are powerfully influencial. These forces are both in harmony and in conflict. They simply exist.
We all have a choice in how we interact with this complex world-system of cause-and-effect.
Choosing not to make contributions (financial, development time, debug time, teaching time, etc) has a cause-and-effect relationship to the human ecosystem.
Let's close this and get back to work
