Ford Foundation:

Our modern society runs on software. But the tools we use to build software are buckling under increased demand.
 
 Nearly all software today relies on free, public code, written and maintained by communities of developers and other talent. This code can be used by anyone—from companies to individuals—to write their own software. Shared, public code makes up the digital infrastructure of our society today.
 
 Everybody relies on shared code to write software, including Fortune 500 companies, government, major software companies and startups. In a world driven by technology, we are putting increased demand on those who maintain our digital infrastructure. Yet because these communities are not highly visible, the rest of the world has been slow to notice.
 
 Just like physical infrastructure, digital infrastructure needs regular upkeep and maintenance. But financial support for digital infrastructure is much harder to come by.
