Open source is solidarity.

"Solidarity is the circumstantial support or adherence to a cause or to the interest of others, for example, in difficult situations. The word solidarity is of Latin origin "solidus" which means "supportive".

When two or more people join together and collaborate mutually to achieve a common goal, we speak of solidarity. Solidarity is sharing with others both materially and sentimentally, it is offering help to others and a mutual collaboration between people."
