Who writes Linux and open source software?

Even though some people think that Linux and Open Source software are only used by developers who love to code as a hobby, recent analysis on GitHub shows that tech giants such as Amazon, Google, Intel, Red Hat, and even Microsoft are among the top contributors to Open Source projects.

In fact, Amazon recently overtook IBM to become the fifth-biggest contributor to Open Source projects.
