Github is a trailblazer here for tech companies taking social impact seriously. There is nothing derogatory about it. They do amazing projects in this area

http://connecthome.hud.gov/
https://github.com/detroitwaterproject/detroit-water-project
I was merely curious about how this fits into their grander strategy.
