Just myself, I saw an increase in FOSS activity seemingly due to the Great Recession leaving so many unemployed. People had so much time on their hands that contributing to a FOSS project made sense for all sorts of reasons. After years of recovery, people are (were?) back employed and don’t have such time on their hands.

FOSS is pretty interesting as a way for otherwise non-cooperatives to make something useful together. Also seems like something similar to academics. Unfortunately, our economic system might force it to be a fluke.
